Legend in React Accumulation Chart component

02 Aug 2021 / 6 minutes to read

As like a chart, the legend is also available for accumulation charts, which gives information about the points. By default, the legend will be placed on the right, if the width of the chart is high or will be placed on the bottom, if the height of the chart is high. Other customization features regarding the legend element are same as the chart legend. Here, the legend for a point can be collapsed by giving the empty string to the x value of the point.

ReactDOM.render(<App />, document.getElementById("charts"));

Note: To use the legends feature, inject the AccumulationLegend using the module into the services.

Position and Alignment

By using the position property, you can position the legend at the left, right, top or bottom of the chart. You can also align the legend to center, far or near of the chart using the alignment property.

By default, the page number will be enabled while legend paging. Now, you can disable that page number and also you can get left and right arrows for page navigation. You have to set false value to enablePages to get this support.
