Title of axes

The title of chart axes can be displayed for the different axes.
Title of axes
The title of the chart axes is defined by grAxisTitle. This function can also be used to position this title according to the desired axis. You cannot define the positioning and/or the orientation of the title in relation to the axis.
The font used for the chart title can be modified by grAxisTitleFont.

Languages that use a non-Latin character set

grAxisTitle will use the selected non-Latin character set only if the associated project configuration uses UNICODE strings at runtime.
To check the selected option in the current configuration:
  1. On the "Project" tab, in the "Project configuration" group, click "Current configuration".
  2. Go to the "Unicode" tab: "Use UNICODE strings at runtime" must be checked.
  3. Validate if necessary.
