The Chart labels property defines which labels are displayed for chart elements.
Chart labels are of value type text. If another value type such as number or date is specified, it is converted into a text.
If a chart label value is empty, no label is displayed for this data set.
In this example, only the value of the largest bar is to be displayed for the bar chart. For this purpose, a table widget is specified which has empty cells except at the position assigned to the corresponding data record in the table.
