description

By default all axis in SciChart have Id=AxisCore.DEFAULT_AXIS_ID. Also, all RenderableSeries have an xAxisId and yAxisId property set to AxisCore.DEFAULT_AXIS_ID. Annotations also have an xAxisId and yAxisId also set to AxisCore.DEFAULT_AXIS_ID. Some Chart Modifiers have an x,yAxisId property to filter their operations to an axis.

In multi-axis scenarios you will need to set the xAxisId/yAxisId properties of series, annotations, modifiers to match that of the axis you want them to be registered on.
