Demonstrates a line chart with four series and multiple top / bottom X-Axis and left / right Y-Axis. SciChart supports multiple top or bottom X-Axes and multiple left and right Y-Axes. This example shows in a simple way how to register a line series on each axis.

Also it is possible to have multiple Y-Axes and create Vertical Charts positioning them vertically.

Example Usage

– Drag any axis to scale.
– Drag the chart to zoom.
– Double click to reset zoom.

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.
