    Hi out there, it seems that the labels of the z-axis (routine: shade_surf) are stretched to the broadness of the labels of the y-axis (please have a look on the screenshot here: https://www.dropbox.com/s/364uulh5tbw... ). In my case, the z-label "200" is stretched to fit the length of the y-label "5334000". How can I prevend this? Parts of the code: !P.BACKGROUND='000000'x !P.COLOR= 'FFFFFF'x !P.FONT=1 shade_surf, data, charsize=1.5, ax=70, zvalue=0.7 ,$ XTITLE="Rechtswert (Gauss-Krueger) [m]",YTITLE="Hochwert (Gauss-Krueger) [m]",ZTITLE="[m]",$ XSTYLE=3,YSTYLE=3,ZSTYLE=3;, Font="Arial" Thanks a lot, Harald

    I would try removing the [XYZ]Style keywords. You are setting them to 3, which both extends the axis (whatever that means) and forces exact axis range (1+2=3). I don't think it is possible to do both of those things at the same time. I think that is what is screwing these labels up for you.

    Thanks a lot for your help. Unfortunately, there is no change in the picture when I omit the [XYZ]STYLE-parameters. The code is: WINDOW, 1, XSIZE=1600, YSIZE=1000, TITLE='Tennenbach' shade_surf, data, charsize=1.5, ax=70, zvalue=0.7 ,$ XTITLE="Rechtswert (Gauss-Krueger) [m]",YTITLE="Hochwert (Gauss-Krueger) [m]",ZTITLE="[m]",$ ZTICKLEN=.02, Font=2 edit: But if I choose another font (FONT=2), then the output of shade_surf looks like this: https://www.dropbox.com/s/m3yu23s2jup... Hmmmm... Harald

    Well, now this is a misuse of the FONT keyword, which can only have the values -1, 0, and 1. I would suggest setting the FONT=1 and changing your true-type font with DEVICE, SET_FONT='whateveryournewfontis', /TT_FONT=1. It appears from the picture that IDL is chosing hardware fonts (FONT=0) in its confusion, and hardware fonts do not rotate. With surfaces, you need Hershey (FONT=-1) or True-Type (FONT=1) fonts.

    @David Fanning: Thanks a lot for your hints, nearly everything works fine now. Unfortunately, the "old" problem persists... :-(

    Well, the shaded surface plot is actually being created as an image in the z-buffer, so this could be a z-buffer problem. The z-buffer has known character size problems. This could be a manifestation of that. Is there any chance you could ditch these direct graphics routines and use object graphics? These routines, my cgSurface, for example, are MUCH better in the 3D world than the 2.5D world of direct graphics. Or, you could try adding your axes after the surface is created. See the Hidden Surface Plot example at the bottom of this page for an example of how that is done. http://www.idlcoyote.com/gallery/index.html
