Chart composition

Creating advanced custom charts.

Overview

The @mui/x-charts follows an architecture based on context providers. The overall idea is to pass your series and axes definitions to a single component: the <ChartContainer />. This component transforms the data and makes it available to its children.

Based on the data provided by the container, you can render some graphical elements with provided subcomponents, such as <LinePlot /> or <ChartsYAxis />. Or you can create your own components.

Container options

Responsive

The <ChartContainer /> is responsive by default. The component automatically adjusts its dimensions to fit the available space defined by the parent element.

To control the dimensions of the chart, the width and height props can be provided. The chart then renders with the specified dimensions.

The following demo lets you switch between a chart using defined sizes, <ChartContainer width={500} height={300} />, and a chart without any sizes, <ChartContainer />, so you can see how they differ.

Properties

The chart container gets all props that are not specific to a single graphical element. This includes:

• The xAxis and yAxis props—find more information in the Axis doc
• The colors prop as defined in the color palette page
• The series and dataset props

Series

The series prop is an array of series definitions. You can find an explanation about each specific series type in their respective docs page: Line, Bar, Pie, and Scatter.

When using a single Charts component, the library can guess which kind of series you are defining. For example, the Bar Chart component assumes that series will be of type 'bar'.

With composition, the chart container isn't able to guess the series type, so you must explicitly define it.

<BarChart
  series={[{
    data: [1, 2, 3] // No need to specify it is a bar series
  }]}
/>

<ChartContainer
  series={[
    { data: [1, 2, 3], type: 'bar' }, // This series is for the bar chart
    { data: [3, 2, 1], type: 'line' } // This series is for the line chart
  ]}
>
  <BarPlot /> {/* Will only display series with type: 'bar' */}
  <LinePlot /> {/* Will only display series with type: 'line' */}
</ChartContainer>

Those series can use the dataset prop the same way that a single-component chart does—see Using a dataset in the Bar Chart documentation for more details.

In the next demo, the chart is made by composing the <BarPlot /> and <LinePlot /> components. By modifying the series type property, you can switch between rendering a line and a bar.

<ChartContainer
  series={[
    { type, data: [1, 2, 3, 2, 1] },
    { type, data: [4, 3, 1, 3, 4] },
  ]}
>
  <BarPlot />
  <LinePlot />
  <ChartsXAxis label="X axis" position="bottom" axisId="x-axis-id" />
</ChartContainer>

Subcomponents

Plotting

To display data, you have components named <XxxPlot /> such as <LinePlot />, <AreaPlot />, <MarkPlot />, <BarPlot />, etc.

Clipping

To ensure chart elements stay confined to the designated drawing area, use the ChartsClipPath component. This component defines a rectangular clip path that acts as a boundary.

1. Define the Clip Path: Use <ChartsClipPath id={clipPathId} /> to establish the clip path for the drawing area. clipPathId must be a unique identifier.
2. Wrap the Chart: Enclose the chart elements you want to clip within a <g> element. Set the clipPath attribute to url(#${clipPathId}) to reference the previously defined clip path. Example: <g clipPath={`url(#${clipPathId})`}>

<ChartContainer>
  <g clipPath={`url(#${clipPathId})`}>
    // The plotting to clip in the drawing area.
    <ScatterPlot />
    <LinePlot />
  </g>
  <ChartsClipPath id={clipPathId} /> // Defines the clip path of the drawing area.
</ChartContainer>

The following demo allows you to toggle clipping for scatter and line plots. Observe how line markers extend beyond the clip area, rendering on top of the axes.

Axis

To add axes, you can use <ChartsXAxis /> and <ChartsYAxis /> as defined in the axis page.

It takes an axisId prop that indicates which axis, defined in the container, should be rendered. If axisId is not provided it will pick the first one.

Grid

To add a grid, you can use the <ChartsGrid /> component.

See Axis—Grid documentation for more information.

Additional information

To add a legend to your chart, you can use <ChartsLegend />.

Most of the props are explained in the legend page. The demos use the slotProps.legend object, but with composition, you can pass props directly to <ChartsLegend />.

// With single component chart
<BarChart
  slotProps={{
    legend: {
      direction: 'row',
    }
  }}
/>

// With composition
<ChartContainer>
  <ChartsLegend direction="row" />
</ChartContainer>

Interaction

You can also add interactive elements such as <ChartsAxisHighlight /> and <ChartsTooltip />.
