A static example which demonstrates a line chart with two series and primary and secondary Y-Axis. SciChart supports unlimited left and right Y-Axes and this example shows in a simple way how to register a line series on each axis.

Tips!

To set axis placement you need to call setAxisAlignment(AxisAlignment) method with appropriate AxisAlignment value

The setAxisId(String) method can used to assign Id to and axis and attach a RenderableSeries to it.

To register RenderableSeries on axis you need to set appropriate xAxisId or yAxisId.
