Combination ChartLocate this document in the navigation structure

Combination charts allow multiple layers of a graph to share the same category, but have their own values and series grouped and drawn in different styles.

A combination chart consist of two components:

  • sap.makit/CombinationChart control

  • sap.makit/Layer element

To create a combination chart, create a CombinationChart control and add multiple Layer elements. The CombinationChart control serves as a container for the combination chart and multiple charts are added by means of 'layers' aggregation: each chart in the CombinationChart is represented by the Layer object. The CombinationChart control contains all the properties, aggregations, events, and methods that are shared by all layers.

Example: The CombinationChart control has a categoryRegions aggregation that is shared by all layers. One of the Layer elements has a type property that only applies to that particular layer.

    Combination Chart with Dual Axis
    The dual axis feature for combination charts allows to define one or more layers to be scaled and drawn based on a secondary value axis. This secondary value axis is usually positioned on the right hand side of the chart or, in case of a bar chart, at the bottom.
