Angular ChartsCombination Charts

Version 14.2.0

A combination chart combines two or more series types allowing for flexible data visualisations. They are ideal for making visual comparisons of different sets of data in a single chart.

Combination Series Types Copy Link

It is possible to create Combination Charts using the following series types: bar, line, area, scatter and bubble.

The type property must be specified explicitly on each individual series object in the series options array, as shown below:

{
    series: [
        {
            type: 'bar', // use 'bar' series
            xKey: 'year',
            yKey: 'men',
            // ...other series options
        },
        {
            type: 'line', // use 'line' series
            xKey: 'year',
            yKey: 'portions',
            // ...other series options
        },
    ],
}

The snippet above shows the configuration required for a combination chart consisting of a bar and line series.

The example below demonstrates two common combination chart types. You can switch between these two combination chart types using the buttons above the chart. Please note:

Series are rendered according to the order in which they are added in the series array.
The area and line series are plotted on a Secondary Axis with a different scale.
