set cthick

This command sets the thickness for the contour lines.

Synatx

set cthick thickness

The thickness arg must be an integer in the range of 1 to 12 (or 256 for version 2.1 and later)

Usage Notes

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 contour lines approximately one pixel wide; a thickness between 6 and 11 will result in contour lines two pixels wide, and a thickness of 12 will give contour lines approximately three pixels wide. For the vector graphics output (e.g. PostScript and Encapsulated PostScript) the contour line thickness will increase with each increment in the thickness value.

If using GrADS version 2.1 and later with the Cairo graphics library enabled, then each thickness setting will increment the contour line thickness, for the X window display and 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 will depend on the surface being drawn to (pixels or points). 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.

The default thickness setting for contour lines is 4. The thickness setting is reset after each clear command, or when a reset or reinit command is issued.

Examples

Note the (2nd example will only work with version 2.1 or later)

set cthick 6

set lwid 13 1.6
set cthick 13

我看的大气研究所的手册说它的值应该是0-9好像，，，所以就过来请教下

最终还是要以grads的官方文档为准，因为大气所的册子很久没更新，而且是别人理解过的东西，不一定全部是对的···但是里面基本没有错误，只是有些小的出入

您有没有发现垂直速度和水汽通量散度、散度的值都很小，和实况不符啊，要不要检查一下哪里出错了，诚建！
