Dear fellow GMT users,
I recently installed the latest GMT version on a new computer and ran older scripts (older but still GMT6). Now labels on color bars are scaled relative to the axes labels (i.e., they are much smaller). I prefer to control the font size myself but don’t find a way to turn this off. Changing the defaults using “gmt set” doesn’t help. Any suggestions?
Thanks!
Classic mode or modern? Maybe play with different GMT_THEME, I think the modern and minimal themes cause auto scaling.
I have tried but changing to classic doesn’t help either.
Yes. A (non) working example.
An example will help as @Joaquim says.
See GMT Themes — GMT 6.6.0 documentation. Both modern and minimal auto scales a lot of settings.
Maybe this can help, Gmt not reading FORMAT_GEO_MAP from gmt.conf - #11 by Andreas?
Here’s the script:
gmt begin SWBaltic
gmt set GMT_THEME classic FONT_ANNOT 12p MAP_FRAME_TYPE plain -JM8c -R9.785/10.6/54.26/54.83
gmt makecpt -Cabyss -T0/50/2 -Iz -H > contour_3.cpt
gmt basemap -Bx0.5g0 -Bya0.25g0 -BWesN
gmt coast -Df -W0.3p -Wblack -Ggray90 -A2000
gmt colorbar -Dx4.5c/+1.0c+w3c/0.3ch -Ccontour_3.cpt -B10 -B+l"Water depth (m)"
gmt basemap -R+7.7/+13.7/+53.5/+57.9 -JM2.2c -Bx0.0g0 -Bya0.0g0 -Bwesn
gmt coast -Dh -W0.3p,black -A2000 -Ggray80 -Swhite
gmt end show
I also copied the modern file in the theme folder, changed all fonts to 12p, renamed it and called it with GMT_THEME. Same unsatisfying result.
Sorry, but please make it a minimal example. Often one liner is all it takes to show the issue.
Here’s a simple example. In the custom theme all fonts are set to 12p. I can modify the frame by changing to plain but I don’t see how I can turn off automatic labeling. Turning off GMT_THEME altogether doesn’t work either.
gmt begin example
gmt set GMT_THEME custom FONT_ANNOT 12p MAP_FRAME_TYPE plain -JM8c -R9.785/10.6/54.26/54.83
gmt makecpt -Cabyss -T0/50/2 -Iz -H > example.cpt
gmt basemap -Bx0.5g0 -Bya0.25g0 -BWesN
gmt colorbar -Dx4.5c/+1.0c+w3c/0.3ch -Cexample.cpt -B10 -B+l"Water depth (m)"
gmt end show
This is a one-liner
gmt colorbar -Dx7.5c/-.85c+w14c/0.15c+jTC+h+e -F+gwhite -B.1g.2 -B+tcontinuous -Cjet -Bx -By+lmm/day --FONT_ANNOT=20 -png lixo
Thanks for the illustration. I added additional lines (base map) to demonstrate the different font size between axes and colorbar labels.
Try removing FONT_ANNOT 12p from your set command and add --FONT_ANNOT_PRIMARY=46p to your colorbar call.
Thanks a lot! The numbers were larger but the title was still small. Using --FONT instead of --FONT_ANNOT_PRIMARY changes both.
