I am trying to create a plot with a colorbar. Since I want uniform, nicely rounded labels, I use a custom label file I create with entries like:
5.0235328493782 a 5
This works as desired when plotting a horizontal colorbar, using a position parameter of JBC
and a frame parameter of pxc<filename>
However, if I switch to a vertical colorbar by changing the position parameter to JMR
, all but the first label disappear.
How might I fix this?
That sounds like a bug. Would you be able to post a but report on GitHub and supply a stripped down script (e.g., just a coast plot instead of grid, make cpt and then your custom table and the colorbar plot) to simplicy debugging for me?
Here’s the translated GMT code
cat << EOF >| annots.txt
0 a 0
5 a 5
10 a 10
15 a 15
20 a 20
EOF
gmt begin colorbarexample png
gmt basemap -JM10i -R-180/-142.119/48.225/65.694 -BWeSn -Bafg
gmt coast -S#CBE7FF -Df
gmt makecpt -Cjet -T0/20
gmt colorbar -DJMR -Bpxcannots.txt
gmt colorbar -DJBC -Bpxcannots.txt
gmt end show
produces
