Remarks

Handling the category labels

The category labels are displayed:
  • below the horizontal marks for Line and Stock charts (Candlestick and BarCharts),
  • below the X-axis for Column and MinMax charts.
Category label
Category labels cannot be used in 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 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.
