This was fixed in an earlier version. If I have one time point with every value exactly zero, nothing happen when I try to plot. This doesn't happen very often but when comparing a forecast with analysis, the first time-step is exactly zero. If I shift the first time to the second time step the plot looks fine. DV3D handle the zero value by just plotting zeros for the entire map.

At that point we diverged too much from original pictures. I cannot/don’t want to regenerate all pix for every branch, please merge all my branches in, they pass tests on my systems. ALL of them. Once they are all in, I will merge master into my logo branch and regenerate all the pix ok?

Thanks,

C.

that might be that the source image is not in the repo actually. Can you double check please. I've only seen this PNG error when source is missing.
