Re: print ignores object properties in 3d

[Ben Abbott]

Hi David,

I understand what you're seeing now.

I'm running gnuplot 4.3 and have no problem printing to a pdf file. I  
thought I had printed to pdf files when I was using 4.2.3 ... can  
someone else comment?

Regarding the zlabel for 3D plots, it appears that octave is not  
setting the zlabel rotation to the default 90 degrees. Unfortunately,  
even when I fix that gnuplot ignores it.

What I can offer you today is a work around. Rather than using  
zlabel("your zlabel"), try

	hz = text(1.15*min (get (gca, "xlim")), 1.15*max (get (gca, "ylim")),  
mean (get (gca, "zlim")), "my rotated zlabel");
        set (hz, "rotation", 90, "horizontalalignment", "center")

If you want to adjust the font size

        set (hz, "fontsize", 12)

Setting the (x,y) position correctly can be a pain if the perspective  
changes.

To fix this correctly, I think gnuplot should be patched so that 3D  
plots respect the specified axis label rotations.
