Invalid annotation phase on exponential axes #8568
Description
Description of the problem
When setting the figure frame, the offset (phase) of annotations is invalid on the exponent axes. For example, setting an exponent axis ranging from 0.05 to 1 scaled by the exponent of 0.2, the annotation interval is 0.2, and the phase is 0.1:
gmt basemap -JX10cp0.2 -R0.05/1/0/1 -Bxa0.2+0.1f0.05 -pdf test-exp-phase
We want to annotate it in the positions 0.1, 0.3,..., but this command produces results marked in 0.2, 0.4,..., same with the command without phase:
gmt basemap -JX10cp0.2 -R0.05/1/0/1 -Bxa0.2f0.05 -pdf test-exp
On the contrary, on the linear axes, it produces correct results:
gmt basemap -JX10c -R0.05/1/0/1 -Bxa0.2+0.1f0.05 -pdf test-lin
