The rendering of charts includes the following elements that are defined in the APF Configuration Modeler:
The chart title is taken from the Step Long Title field of the step configuration. It is displayed above any representation of a particular analysis step. If no long title is defined, the step title is used instead.
Titles of the horizontal axis and the vertical axis
The general format of the title is <title (unit)>. It can be determined in one of the following ways:
The title is first read from the Label field of the representation configuration in the APF Configuration Modeler, if this property has been configured.
If the fieldDesc property has not been configured, but the field has a corresponding sap:text annotation in the OData metadata, the system looks up the field name specified in the annotation and retrieves the sap:label value of that field. This applies to those fields for which you want to display the name rather than an ID, for example, the customer ID.
If the Label field has not been configured and a sap:text annotation does not exist, the system looks up the sap:label annotation of the OData metadata, which retrieves the label specified for this field in the SAP HANA model.
Value formatting rules:
All fields of type CalendarYearMonth are formatted to MM YYYY.
If a sap:text annotation exists in the metadata of a field, the value is formatted to textValue (keyValue), where textValue is the value of the sap:text field, and keyValue is the value of the actual field, which is given as dimension or measure.
In all other cases, the value is displayed without any formatting.
A legend is displayed for all charts that have multiple dimensions or measures. The values can be formatted as described in the value formatting rules.
Labels of the horizontal axis and the vertical axis
The rendering of the labels of the axes is defined by the behavior of the core chart. The values can be formatted as described in the value formatting rules.
