Pie graph: Data Label group
Properties in this group control the labels that are in the legend and in tooltips.
Data Label properties
The group contains the following properties:
columnDisplayNames
Set alternate display names for the columns of the data attached to
valueTable. Column names are displayed in the legend, if
rowSeriesFlag is selected.
This property is in the Data Label property group.
labelColumnName
Sets the label column. By default, the label column is the first non-numeric text column in your data attachment, if there is one. Note that the column apama.instanceID (contained in all DataView instance tables) is a non-numerical text column.
Data from the label column is used to label the legend, if
rowSeriesFlag is disabled. Data from the label column is used in tooltips, if
rowSeriesFlag and
mouseOverFlag are enabled.
This property is in the Data Label property group.
rowLabelVisFlag
Determines whether or not data from the label column is used in the chart legend, when
rowSeriesFlag is disabled. See
labelColumnName. If
rowLabelVisFlag is disabled, integer row identifiers are used in the legend.
This property is in the Data Label property group.
rowNameVisFlag
If your data attachment has no label column (see
labelColumnName), select this property to use generated row names in the legend when the
rowSeriesFlag is not selected.
This property is in the Data Label property group.
