set ylopts

This command controls the appearance of the tic labels on the Y axis.


set ylopts color <thickness <size>>

Usage Notes

This setting 'sticks' until changed by issuing another set ylopts command, or when a reset or reinit command is issued.

If you want to change only the size setting, you must include a color and 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 in the thickness value.

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.

Contour labels drawn with Cairo fonts will not be affected by the set xlopts thickness setting. Please read the documentation page on Font Control in GrADS for more information.

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.
