1.6.1.2 Options for exponential axes

Append p to tick, and the annotation interval is expected to be in transformed units, but annotation will be plotted as un-transformed units. E.g., if tick = 1 and power = 0.5 (i.e., sqrt), then equidistant annotations labeled 1, –4, –9, ... will appear.

Figure 1.8: Exponential or power projection axis. (top) Using an exponent of 0.5 yields a $\sqrt {x}$ 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 anotation uses the corresponding unprojected values, as in -Ba3f2g1p.
