This command controls the appearance of the tic labels on the X axis.
set xlopts color <<thickness <size>
colorLabel color (Default 1)
thicknessLabel thickness (Default 3)
sizeLabel size (Default 0.11)
This setting 'sticks' until changed by issuing another
set xlopts command, or when a
reinit command is issued.
If you want to change only the
size setting, you must include a
thickness setting as well.
When using grads version 2.0.2 and earlier, for the X window display and the image output (e.g. PNG), a
thickness setting between 1 and 5 will result in axis labels approximately one pixel wide; a
thickness between 6 and 11 will result in axis labels two pixels wide, and a
thickness of 12 will give axis labels approximately three pixels wide.
For the vector graphics output (e.g. PostScript and Encapsulated
PostScript) the axis label thickness will increase with each increment
If using grads version 2.1 and later with the Cairo graphics library enabled, and if using Hershey fonts, then each
thickness setting will increment the axis label thickness, for both the X window display and for all hardcopy output formats.
The default line widths for
thickness settings between 1 and 12 are:
0.6, 0.8, 1.0, 1.25, 1.5, 1.75, 2.0, 2.2, 2.4, 2.6, 2.8, 3.0. The units (pixels or points) will depend on the surface being drawn to. In grads version 2.1 and later, there is a new command,
set lwid, that allows the user to define a new line thickness setting if the 12 default widths are unsatisfactory.
