Multiple Axes
You can display the Chart component with multiple axes for better data visualization. This demo illustrates a chart with two separate axes that display percentage and absolute values.
To configure a multi-axis chart, follow the steps below:
-
Create and name value axes. Declare multiple objects in the valueAxis array. Each object configures a value axis. Every value axis should have a unique name.
-
Bind series to value axes.
Assign the name of an axis to the series.axis property. If leave the series.axis property unspecified, the series is bound to the axis declared first in the valueAxis array.
In this demo, the first axis is declared without a name and is bound to the first series. The name of the second axis is total and it is bound to the spline series. The position of the second axis is right.
