- 4.4. The plot region can be specified in two different ways. (a) Extreme values
for each dimension, or (b) coordinates of lower left and upper right corners.
- . The 30+ map projections and coordinate transformations available in GMT.
- . Geographic map border using separate selections for annotation,
frame, and grid intervals. Formatting of the annotation is controlled by
the parameter PLOT_DEGREE_FORMAT in your .gmtdefaults4 file.

- 4.8. Linear Cartesian projection axis. Long tickmarks accompany
annotations, shorter ticks indicate frame interval. The axis label is
optional. We used -R0/12/0/1 -JX3/0.4
-Ba4f2g1:Frequency::,%:.
- 4.9. Logarithmic projection axis using separate values for annotation,
frame, and grid intervals. (top) Here, we have chosen to annotate the actual
values. Interval = 1 means every whole power of 10, 2 means 1, 2, 5 times
powers of 10, and 3 means every 0.1 times powers of 10. We used
-R1/1000/0/1 -JX3l/0.4 -Ba1f2g3.
(middle) Here, we have chosen to
annotate log
of the actual values, with -Ba1f2g3l.
(bottom) We annotate every power of 10 using log
of the actual values
as exponents, with -Ba1f2g3p.
- 4.10. Exponential or power projection axis. (top) Using an exponent of 0.5
yields a
axis. Here, intervals refer to actual data values, in
-R0/100/0/1 -JX3p0.5/0.4 -Ba20f10g5.
(bottom) Here, intervals refer to projected values, although the annotation
uses the corresponding unprojected values, as in -Ba3f2g1p.

- . Chartreuse in GIMP. (a) Sliders indicate how the color is altered when changing the H, S, V, R, G, or B levels. (b) For a constant hue (here 90°) value increases to the right and saturation increases up, so the ``pure'' color is on the top right.
- I.2. The 555 unique color names that can be used in GMT. Lower, upper, or mixed case, as well as the british
spelling of ``grey'' are allowed. A4, Letter, and Tabloid sized versions of this RGB chart can be found in the
GMT documentation directory.
- I.3. The HSV color space.
- . When interpolating colors, the color system matters. The polar palette on the left needs to be interpolated in RGB, otherwise hue will change between blue (240°) and white (0°). The rainbow palette should be interpolated in HSV, since only hue should change between magenta (300°) and red (0°). Diamonds indicate which colors are defined in the palettes; they are fixed, the rest is interpolated.
