Charts

Bootstrap 5 Charts

MDB charts are visual representations of data. They are responsive and easy to customize. At your disposal are eight types of charts with multiple options for customization.

Note: Read the API tab to find all available options and advanced customization.

Note 2: See also advanced charts documentation to see an implementation of the advanced options.

Bar chart

You can initialize simple charts with data-mdb-attributes - it doesn't require any additional JS code.

Note: This method allows only one dataset - more complicated charts require JavaScript initialization.

Via data-mdb-attributes:

        
            
          <canvas
            data-mdb-chart="bar"
            data-mdb-dataset-label="Traffic"
            data-mdb-labels="['Monday', 'Tuesday' , 'Wednesday' , 'Thursday' , 'Friday' , 'Saturday' , 'Sunday ']"
            data-mdb-dataset-data="[2112, 2343, 2545, 3423, 2365, 1985, 987]"
          ></canvas>
        
        
    

The same effect achieved via Javascript initialization:

        
            
          <canvas id="bar-chart"></canvas>
        
        
    
        
            
            // Chart
            const dataBar = {
              type: 'bar',
              data: {
                labels: ['Monday', 'Tuesday' , 'Wednesday' , 'Thursday' , 'Friday' , 'Saturday' , 'Sunday '],
                datasets: [
                  {
                    label: 'Traffic',
                    data: [2112, 2343, 2545, 3423, 2365, 1985, 987],
                  },
                ],
              },
            };

            new mdb.Chart(document.getElementById('bar-chart'), dataBar);
        
        
    

Line chart

To use our minimalistic line chart, set the type option to line.

Via data-mdb-attributes:

        
            
          <canvas
            data-mdb-chart="line"
            data-mdb-dataset-label="Traffic"
            data-mdb-labels="['Monday', 'Tuesday' , 'Wednesday' , 'Thursday' , 'Friday' , 'Saturday' , 'Sunday ']"
            data-mdb-dataset-data="[2112, 2343, 2545, 3423, 2365, 1985, 987]"
          ></canvas>
        
        
    

Via JavaScript:

        
            
          <canvas id="line-chart"></canvas>
        
        
    
        
            
          // Chart
          const dataLine = {
            type: 'line',
            data: {
              labels: ['Monday', 'Tuesday' , 'Wednesday' , 'Thursday' , 'Friday' , 'Saturday' , 'Sunday '],
              datasets: [
                {
                  label: 'Traffic',
                  data: [2112, 2343, 2545, 3423, 2365, 1985, 987],
                },
              ],
            },
          };

          new mdb.Chart(document.getElementById('line-chart'), dataLine);
        
        
    

Bar chart horizontal

Change the orientation of your bar chart from vertical to horizontal by setting the indexAxis option to 'y'.

        
            
          <canvas id="bar-chart-horizontal"></canvas>
        
        
    
        
            
          // Chart
          const dataBarHorizontal = {
            type: 'bar',
            data: {
              labels: ['January', 'February', 'March', 'April', 'May', 'June', 'July'],
              datasets: [
                {
                  label: 'Traffic',
                  data: [30, 15, 62, 65, 61, 65, 40],
                },
              ],
            },
          };
    
          const optionsBarHorizontal = {
            options: {
              indexAxis: 'y',
              scales: {
                x: {
                  stacked: true,
                  grid: {
                    display: true,
                    borderDash: [2],
                    zeroLineColor: 'rgba(0,0,0,0)',
                    zeroLineBorderDash: [2],
                    zeroLineBorderDashOffset: [2],
                  },
                  ticks: {
                    color: 'rgba(0,0,0, 0.5)',
                  },
                },
                y: {
                  stacked: true,
                  grid: {
                    display: false,
                  },
                  ticks: {
                    color: 'rgba(0,0,0, 0.5)',
                  },
                },
              },
            },
          };
    
          new mdb.Chart(document.getElementById('bar-chart-horizontal'), dataBarHorizontal, optionsBarHorizontal);
        
        
    

Pie chart

A chart with the type pie splits the circle into several pieces to represent a dataset's values as an area's percentage.

Via data-mdb-attributes:

        
            
          <canvas
            data-mdb-chart="pie"
            data-mdb-dataset-label="Traffic"
            data-mdb-labels="['Monday', 'Tuesday' , 'Wednesday' , 'Thursday' , 'Friday' , 'Saturday' , 'Sunday ']"
            data-mdb-dataset-data="[2112, 2343, 2545, 3423, 2365, 1985, 987]"
            data-mdb-dataset-background-color="['rgba(63, 81, 181, 0.5)', 'rgba(77, 182, 172, 0.5)', 'rgba(66, 133, 244, 0.5)', 'rgba(156, 39, 176, 0.5)', 'rgba(233, 30, 99, 0.5)', 'rgba(66, 73, 244, 0.4)', 'rgba(66, 133, 244, 0.2)']"
          ></canvas>
        
        
    

Via JavaScript:

        
            
          <canvas id="pie-chart"></canvas>
        
        
    
        
            
          // Chart
          const dataPie = {
            type: 'pie',
            data: {
              labels: ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday '],
              datasets: [
                {
                  label: 'Traffic',
                  data: [2112, 2343, 2545, 3423, 2365, 1985, 987],
                  backgroundColor: [
                    'rgba(63, 81, 181, 0.5)',
                    'rgba(77, 182, 172, 0.5)',
                    'rgba(66, 133, 244, 0.5)',
                    'rgba(156, 39, 176, 0.5)',
                    'rgba(233, 30, 99, 0.5)',
                    'rgba(66, 73, 244, 0.4)',
                    'rgba(66, 133, 244, 0.2)',
                  ],
                },
              ],
            },
          };

          new mdb.Chart(document.getElementById('pie-chart'), dataPie);
        
        
    

Doughnut chart

Another type of graph representing data as an area's percentage is a doughnut chart.

Via data-mdb-attributes:

        
            
          <canvas
            data-mdb-chart="doughnut"
            data-mdb-dataset-label="Traffic"
            data-mdb-labels="['Monday', 'Tuesday' , 'Wednesday' , 'Thursday' , 'Friday' , 'Saturday' , 'Sunday ']"
            data-mdb-dataset-data="[2112, 2343, 2545, 3423, 2365, 1985, 987]"
            data-mdb-dataset-background-color="['rgba(63, 81, 181, 0.5)', 'rgba(77, 182, 172, 0.5)', 'rgba(66, 133, 244, 0.5)', 'rgba(156, 39, 176, 0.5)', 'rgba(233, 30, 99, 0.5)', 'rgba(66, 73, 244, 0.4)', 'rgba(66, 133, 244, 0.2)']"
          ></canvas>
        
        
    

Via JavaScript:

        
            
          <canvas id="doughnut-chart"></canvas>
        
        
    
        
            
          // Chart
          const dataDoughnut = {
            type: 'doughnut',
            data: {
              labels: ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday '],
              datasets: [
                {

                  ],
                },
              ],
            },
          };

          new mdb.Chart(document.getElementById('doughnut-chart'), dataDoughnut);
        
        
    

Polar chart

Polar area graph will split the circle into pieces with equal angles and different radius.

Via data-mdb-attributes:

        
            
          <canvas
            data-mdb-chart="polarArea"
            data-mdb-dataset-label="Traffic"
            data-mdb-labels="['Monday', 'Tuesday' , 'Wednesday' , 'Thursday' , 'Friday' , 'Saturday' , 'Sunday ']"
            data-mdb-dataset-data="[2112, 2343, 2545, 3423, 2365, 1985, 987]"
            data-mdb-dataset-background-color="['rgba(63, 81, 181, 0.5)', 'rgba(77, 182, 172, 0.5)', 'rgba(66, 133, 244, 0.5)', 'rgba(156, 39, 176, 0.5)', 'rgba(233, 30, 99, 0.5)', 'rgba(66, 73, 244, 0.4)', 'rgba(66, 133, 244, 0.2)']"
          ></canvas>
        
        
    

Via JavaScript:

        
            
          <canvas id="polar-area-chart"></canvas>
        
        
    
        
            
          // Chart
          const dataPolar = {
            type: 'polarArea',

                    'rgba(66, 133, 244, 0.5)',
                    'rgba(156, 39, 176, 0.5)',
                    'rgba(233, 30, 99, 0.5)',
                    'rgba(66, 73, 244, 0.4)',
                    'rgba(66, 133, 244, 0.2)',
                  ],
                },
              ],
            },
          };

          new mdb.Chart(document.getElementById('polar-area-chart'), dataPolar);
        
        
    

Radar chart

This type of chart will enclose the area based on a dataset's values.

Via data-mdb-attributes:

        
            
          <canvas
            data-mdb-chart="radar"
            data-mdb-dataset-label="Traffic"
            data-mdb-labels="['Monday', 'Tuesday' , 'Wednesday' , 'Thursday' , 'Friday' , 'Saturday' , 'Sunday ']"

          ></canvas>
        
        
    

Via JavaScript:

        
            
      <canvas id="radar-chart"></canvas>
    
        
    
        
            
      // Chart
      const dataRadar = {
        type: 'radar',

              data: [2112, 2343, 2545, 3423, 2365, 1985, 987],
            },
          ],
        },
      };

      new mdb.Chart(document.getElementById('radar-chart'), dataRadar);
    
        
    

Bubble chart

This graph visualizes data in a series of "bubbles" with customized coordinates and radius.

Note: As mentioned before, charts with more than 1 dataset be used via data-mdb-attributes. All more complicated structures require initialization via JavaScript.

        
            
          <canvas id="bubble-chart"></canvas>
        
        
    
        
            
          // Chart
          const dataBubble = {
            type: 'bubble',
            data: {
              datasets: [
                {
                  label: 'John',
                  data: [
                    {
                      x: 3,
                      y: 7,
                      r: 10,
                    },
                  ],
                  backgroundColor: '#ff6384',
                  hoverBackgroundColor: '#ff6384',
                },
                {
                  label: 'Peter',
                  data: [
                    {
                      x: 5,
                      y: 7,
                      r: 10,
                    },
                  ],
                  backgroundColor: '#44e4ee',
                  hoverBackgroundColor: '#44e4ee',
                },
                {
                  label: 'Donald',
                  data: [
                    {
                      x: 7,
                      y: 7,
                      r: 10,
                    },
                  ],
                  backgroundColor: '#62088A',
                  hoverBackgroundColor: '#62088A',
                },
              ],
            },
          };

          new mdb.Chart(document.getElementById('bubble-chart'), dataBubble);
        
        
    

Scatter chart

Use this chart to represent your data as a series of points with x and y coordinates.

Note: This chart also requires initialization via JavaScript. Initialization via data-mdb-attributes is not possible.

        
            
          <canvas id="scatter-chart"></canvas>
        
        
    
        
            
          // Chart

Bar chart with custom options

MDB provides default options for each chart - you can easily change that by passing an object with your custom options to the Chart constructor.

Note: Read API tab to learn more about available options.

Charts - API

In this section, you will find advanced information about the Chart component. You will learn which modules are required in this component, what are the possibilities of configuring the component, and what events and methods you can use in working with it.


Usage

Via data attributes

You can initialize a simple chart without using additional JavaScript code - just set data-mdb-chart to a selected chart's type (f.e. 'line', 'bar').

Note: Scatter and bubble charts has to be initialized with JavaScript.

Name Type Description
data-mdb-chart String Attribute responsible for initialization and defining a type.
data-mdb-labels String Labels for x-axis
data-mdb-dataset-label String Label values ​​for datasets
data-mdb-dataset-background-color Color[ ] A single color or an array of colors for datasets
data-mdb-dataset-border-color Color[ ] A single border or line color or an array of border colors for datasets
data-mdb-dataset-border-width Number[ ] Single border thickness or a border thickness table for datasets
data-mdb-dataset-data Number[ ] Value sets for charts
        
            
        <canvas
          class="col-sm-12 col-md-10 col-xl-8 mb-4"
          data-mdb-chart="bar"
          data-mdb-dataset-label="Traffic"
          data-mdb-labels="['Monday', 'Tuesday' , 'Wednesday' , 'Thursday' , 'Friday' , 'Saturday' , 'Sunday ']"
          data-mdb-dataset-data="[2112, 2343, 2545, 3423, 2365, 1985, 987]"
        ></canvas>
        
        
    

Via JavaScript

When using the Chart constructor to initialize an instance, you can specify three parameters. The first argument is a wrapper element for a chart, second is a data object with necessary information about displayed datasets. The last are options - each Chart has its default settings provided by the component, so this parameter is optional.

        
            
        <canvas id="bar-chart"></canvas>
    
        
    
        
            
        // Bar chart
        const dataBar = {
          type: 'bar',
          data: {
            labels: ['January', 'February', 'March', 'April', 'May', 'June', 'July'],
            datasets: [
              {
                label: 'Traffic',
                data: [30, 15, 62, 65, 61, 65, 40],
              },
            ],
          },
        };

        new mdb.Chart(document.getElementById('bar-chart'), dataBar);
    
        
    

Via jQuery

Note: By default, MDB does not include jQuery and you have to add it to the project on your own.

        
            
        <canvas id="bar-chart"></canvas>
    
        
    
        
            
        // Bar chart
        const dataBar = {
          type: 'bar',
          data: {
            labels: ['January', 'February', 'March', 'April', 'May', 'June', 'July'],
            datasets: [
              {
                label: 'Traffic',
                data: [30, 15, 62, 65, 61, 65, 40],
              },
            ],
          },
        };

        $('#bar-chart').chart(dataBar);
    
        
    

Options

Line options

The line chart allows specifying several properties for each dataset. Besides, some of them (f.e. all point* properties) can be defined as an array - this way the first value applies to the first point, the second to the second point, etc.

Name Type Description
label String The label for the dataset that appears in the legend and tooltips.
xAxisID String The ID of the x-axis to plot this dataset on. If not specified, this defaults to the ID of the first found x-axis
yAxisID String The ID of the y-axis to plot this dataset on. If not specified, this defaults to the ID of the first found y-axis.
backgroundColor Color The fill color under the line.
borderColor Color The color of the line.
borderWidth Number The width of the line in pixels.
borderDash Number The length and spacing of dashes.
borderDashOffset Number Offset for line dashes.
borderCapStyle String Cap style of the line.
borderJoinStyle String Line joint style.
cubicInterpolationMode String The algorithm used to interpolate a smooth curve from the discrete data points.
fill Boolean/String How to fill the area under the line.
lineTension Number Bezier curve tension of the line. Set to 0 to draw straight lines. This option is ignored if monotone cubic interpolation is used.
pointBackgroundColor Color/Color[ ] The fill color for points.
pointBorderColor Color/Color[ ] The border color for points.
pointBorderWidth Number/Number[ ] The width of the point border in pixels.
pointRadius Number/Number[ ] The radius of the point shape. If set to 0, the point is not rendered.
pointStyle String/String[ ]/Image/Image[ ] Style of the point.
pointRotation Number/Number[ ] The rotation of the point in degrees.
pointHitRadius Number/Number[ ] The pixel size of the non-displayed point that reacts to mouse events.
pointHoverBackgroundColor Color/Color[ ] Point background color when hovered.
pointHoverBorderColor Color/Color[ ] Point border color when hovered.
pointHoverBorderWidth Number/Number[ ] The border width of a point when hovered over.

Scatter chart

Scatter chart displays the dataset as a series of points with z and y coordinates.

The scatter chart supports the same properties as the line chart.


Plugin Legend

Name Type Default Description
display Boolean true showing legend
position String 'top' Position of the legend.
fullWidth Boolean true Marks that this box should take the full width of the canvas (pushing down other boxes). This is unlikely to need to be changed in day-to-day use.
onClick Function

A callback that is called when a click event is registered on a label item

onHover Function

A callback that is called when a 'mousemove' event is registered on top of a label item

reverse Boolean false

Legend will show datasets in reverse order.

labels Object

See documentation about labels in table below.


Plugin Legend - Label Configuration

Name Type Default Description
boxWidth Number 40 width of coloured box
font.size Number 12 font size of text
font.style String 'normal' font style of text
color Color '#666'

Methods

Name Description Example
update(data, config) Updates chart's data and calls .update(config) method instance.update(data, { duration: 800})
dispose Removes a mdb.Chart instance instance.dispose()
getInstance Static method which allows you to get the chart instance associated to a DOM element. Chart.getInstance(chartEl)
getOrCreateInstance Static method which returns the chart instance associated to a DOM element or create a new one in case it wasn't initialized. Chart.getOrCreateInstance(chartEl)
        
            
        const instance = new mdb.Chart(el, data, options);

        instance.dispose();
    
        
    

Events

Event handling in Charts differs from other MDB components - in the options parameter you can define which events should be triggered and handlers for some of them (click, hover).

Name Type Default Description
events string[ ] ['mousemove', 'mouseout', 'click', 'touchstart', 'touchmove'] The events option defines the browser events that the chart should listen to for tooltips and hovering.
onHover function null Called when any of the events fire. Called in the context of the chart and passed the event and an array of active elements (bars, points, etc).
onClick function null Called if the event is of type 'mouseup' or 'click'. Called in the context of the chart and passed the event and an array of active elements.
        
            
          const eventOption = {
            options: {
              // This chart will not respond to mousemove, etc
              events: ['click']
            }
          };
        
        
    

Import

MDB UI KIT also works with module bundlers. Use the following code to import this component:

        
            
        import { Chart } from 'mdb-ui-kit';
