The first two options are permanent changes until explicitly changed back, while the last option is ephemeral and only applies to the single <b><A HREF="GMT.html">GMT</A></b> command that received the override. <b><A HREF="GMT.html">GMT</A></b> can provide default values in US or SI units.

Specify either none (in which case there is no special handling) or <i>pc_lat</i>/<i>pc_dlon</i>.

Note for r-theta (polar) projection where r = 0 is at the center of the plot the meaning of the cap is reversed, i.e., the default 85/90 will draw a r = 5 radius circle at the center of the map with less frequent radial lines there.</p> <p style="margin-left:11%;"><b><A NAME="PS_COLOR">PS_COLOR</A></b></p> <p style="margin-left:22%;">Determines whether <i>PostScript</i> output should use RGB, HSV, CMYK, or GRAY when specifying color [rgb].

When the angle between joining line segments is smaller than the threshold the corner will be bevelled instead of mitered. The default threshold is 35 degrees. Setting the threshold angle to 0 implies the <i>PostScript</i> default of about 11 degrees. Setting the threshold angle to 180 causes all joins to be beveled.</p> <p style="margin-left:11%;"><b><A NAME="PS_VERBOSE">PS_VERBOSE</A></b></p> <p style="margin-left:22%;">If TRUE we will issue comments in the <i>PostScript</i> file that explain the logic of operations.

In the following discussion, the unit <b>u</b> can be one of these time units: (<b>y</b> year, <b>o</b> month, <b>u</b> ISO week, <b>d</b> day, <b>h</b> hour, <b>m</b> minute, and <b>c</b> second). <b><A HREF="gmtdefaults.html#TIME_IS_INTERVAL">TIME_IS_INTERVAL</A></b> can have any of the following three values: (1) OFF [Default]. No adjustment, time is decoded as given. (2) +<i>n</i><b>u</b>. Activate interval adjustment for input by truncate to previous whole number of <i>n</i> units and then center time on the following interval. (3) -<i>n</i><b>u</b>. Same, but center time on the previous interval. For example, with <b><A HREF="gmtdefaults.html#TIME_IS_INTERVAL">TIME_IS_INTERVAL</A></b> = +1o, an input data string like 1999-12 will be interpreted to mean 1999-12-15T12:00:00.0 (exactly middle of December), while if <b><A HREF="gmtdefaults.html#TIME_IS_INTERVAL">TIME_IS_INTERVAL</A></b> = OFF then that date is interpreted to mean 1999-12-01T00:00:00.0 (start of December) [OFF].</p> <p style="margin-left:11%;"><b><A NAME="TIME_LANGUAGE">TIME_LANGUAGE</A></b></p> <p style="margin-left:22%;">Language to use when plotting calendar items such as months and days.
