The maximum length of the text is 100 chars. If the label axis has an alignment of RMC_LABELXISLEFT, the text is drawn vertically from bottom to top, if the alignment is RMC_LABELXISRIGHT, the text is painted vertically from top to bottom, in other cases it is painted horizontally.
As default the text will be printed in the same font size as the axis labels (see FontSize), but you can set the font's size and weight independently: add a backslash (\) at the end of the text, followed by a number and/or the char b, if you want to have the text printetd bold.
