Re: [yt-users] setting limits of the colorbar

Hi Matt, thanks for the fix, it works as expected! I would add a small suggestion: now the user can set the color scale between zmin and zmax, and the color is set to white (or background) for z > zmax or z < zmin. For visualisation purposes, maybe it would be more appropriate to set the color to "color(zmax)" (upper boundary of the color scale) for z > zmax, whereas the white background for z < zmin is certainly more readable. But this is probably a matter of taste... the tool is OK also as it is now, provided the extremes are wisely chosen by the user. Cheers, Luigi Quoting Matthew Turk :

Hi Luigi,

You're actually doing everything correctly -- there was just a bug! It had been fixed in trunk, but not in the yt-1.0 branch, so I went ahead and backported it. If you execute "svn up" in your src/yt directory, it should work now. (Depending on which version of the installation script you have, rerunning it should also work. You may also have to execute "python2.5 setup.py develop" in the yt directory.)

Let me know if there are any more problems -- but I was able to replicate your problem, and the committed change in r1130 has fixed it for me. Good luck!

Dear all,

I am currently trying to plot a 2D phase diagram (T vs rho). The plot is OK, but I have problems with setting the limits of the colorbar (where CellMassMsun is color-coded). Somehow, they are set automatically, which is bad, because I need to compare several plots of different datasets. The set_zlim command does not apparently affect the plot. I copy here my script, and I hope for some suggestions of yours. Thanks in advance,

Luigi
