Hello guys,
I’m struggling here with a 3D perspective where I want to put a “2D plane” title over the figure. I’ve read the other threads on the subject but as much as I add ‘+t"Whatever"’ to the frame it gives me an error or it doesn’t plot.
What am I doing wrong ?
Here is the extract from the main line with grdview. Everything else works.
fig.grdview(grid=-dset.sel(time_d=92).paleobat,
region=region,
perspective=[135,30],
projection=‘X12c’, # set the projection
zsize=‘5c’,
surftype=‘i’,
frame=[‘xa+l"UTM Easting"’,‘ya+l"UTM Northing"’,‘SEwn’],
cmap=‘earth’,
plane=“-3000+ggrey”, # set the plane of the map
shading=‘+a20+nt1’)
Can you show us the error you have?
Here is an example showing how to add a title in a 3D map, although it’s not using grdview:
Hello @seisman,
yes, i tried it exactly as shown in the example. It seems to me that it is a problem with grdview in perspective.
I added now
frame=[‘xa+l"UTM Easting"’,‘ya+l"UTM Northing"’,‘+t"Whatever"’,‘SEwn’],
and the error is this one:
grdview [ERROR]: Option -B parsing failure. Correct syntax:
-B Specify both (1) basemap frame settings and (2) axes parameters.
Frame settings are modified via an optional single invocation of -B[<axes>][+b][+g<fill>][+i[<val>]][+n]⏎
…[+o<lon>/<lat>][+s<subtitle>][+t<title>][+w[<pen>]][+x<fill>][+y<fill>] [+z<fill>]

details and examples of all settings.
grdview [ERROR]: Offending option -BSEwn
The error is apparently restricted to the perspective grdview (when the title has to appear in 2d). I remember seeing some comment on the forum about this but I couldn’t find again what the topic was.
Does this work for you?
frame=['xa+l"UTM Easting"', 'ya+l"UTM Northing"', 'SEwn+t"Whatever"'],
This is pretty weird. When I do this (I did it before), the error is gone but there is no title in the figure:
Any ideas ? I can write dow the program and the datra in gdrive if someone want to try.
I think, the title is there, behind the figure, and is plotted in perspective too.
Yes, it’s behind the figure. Perhaps you can increase MAP_TITLE_OFFSET to see it?
Sorry for the long delay.
Yes - with a title offset I can see it but it’s in 3D ! The only way to have a 2D title in a 3D map is using a basemap and the plot3D inside (at least the solution I found).
