Syntax

Defining the font used for the chart labels Hide the details

<Chart control>.LabelFont(<Font used>)

<Chart control>: Control name

Name of the Chart control found in the report editor.
Only the interactive Chart controls are available.

<Font used>: Font

Font to use. This parameter corresponds to a Font variable. The font characteristics have been defined by FontCreate or via the properties for font management.

Defining the font used for the chart labels (syntax kept for backward compatibility) Hide the details

<Chart control>.LabelFont(<Font identifier>)

<Chart control>: Control name

Name of the Chart control found in the report editor.
Only the interactive Chart controls are available.

<Font identifier>: Integer

Font identifier, defined by grCreateFont. A WLanguage error occurs if this font does not exist.

Remarks

Handling the category labels

The category labels are displayed:

below the horizontal marks for the Line charts and Stock charts (Candlestick and BarCharts),
below the X axis for the column charts and MinMax charts.

The category labels cannot be used with the Scatter charts.

The category labels are defined by <Chart>.CategoryLabel.

The label font can be modified by <Chart>.LabelFont.

The category labels defined by <Chart>.CategoryLabel can be displayed in the caption of the Pie chart (grShowLabel constant used with <Chart>.Label).

Initializing the fonts

The default font used for the labels has the following characteristics:

Font name: Arial
Size: 14
Style: Normal
Color: Black

Orientation of the font

For the labels of a chart, the "orientation" property of the font is ignored.

To change the orientation of the font in the labels, the description of the Chart control must be modified in the 7-tab window.

By default, the orientation is automatically chosen. This orientation takes into account the size and the number of labels to display.
