Dear Ferret users,
I hope this email finds you well.
I am writing regarding some contour labels. I am using PyFerret v7.63 on Linux Ubuntu (via miniconda) but I have the same issues with PyFerret v7.62 and ferret v6.71.
I noticed a problem in the number of colors associated with the FILL or SHADE commands. When I use SHADE and I increase the number of levels, there are some cases for which the last level range is not drawn and is missing in the color scale. It happens when the quantity drawn is small (for instance wind stress in N/m2).
Here are 3 examples:
use coads_climatology.cdf
shade/x=50w:20e/y=30s:30n/levels=(14,29,1) SST[l=@ave]
---> 15 color levels, with levels 0(1), the colorscale is OK
shade/x=50w:20e/y=30s:30n/levels=(0.014,0.029,0.001) SST[l=@ave]/1000
---> 15 color levels, with levels 0(1/1000), the colorscale is missing the last level
shade/x=50w:20e/y=30s:30n/levels=(0.014,0.028,0.001) SST[l=@ave]/1000
---> 14 colors levels with levels 0(1/1000), the colorscale is OK
fill/x=50w:20e/y=30s:30n/levels=(0.0014,0.0029,0.0001) SST[l=@ave]/10000
---> 15 colors levels with levels 0(1/10000), the colorscale is missing the last level
I could not find any rules for which it happens. I thought at first that it is linked to the number of levels, but I found counter-examples (see my last example above).
Maybe this issue has already been reported?
Have a nice day,
Serena Illig
