Syntax

grLabel(<Chart name> , <Additional legend> , <Display>)

<Chart name>: Character string (with or without quotes)

Name of chart to use. This name corresponds to:
the chart name defined by programming with grCreate.
the name of Chart control found in the window editor, page editor or report editor.
Only the Chart controls are available.
Only the interactive Chart controls are available.

<Additional legend>: Constant

Additional legend that will be displayed with the chart:
with a pie chart:
grShowLabel Label of data categories.
grShowPercent Percentage of data categories.
grShowValue Value of data categories.
with a column chart:
grShowValue Value of data categories.
with a stacked column chart:
grShowValueIfNull Label of data categories, even for the null values in the stacked column chart.

<Display>: Boolean

False otherwise.

Remarks

Chart caption

The chart caption can include three elements:

the category labels.
the value of categories.
the percentage of categories.

The chart caption can be displayed for the pie charts, column charts and stacked column charts only.

grLabel is used to display the different elements of the chart caption. Different elements are displayed according to the type of chart.

The category labels displayed correspond to the ones defined by grCategoryLabel.

The value of categories depends on the chart data.

The percentage of categories is automatically calculated.

The information display can be formatted by grMask.

The modifications performed by grLabel will be taken into account during the next call to grDraw.
