Minor
The remaining issue here is that heatmap colour bar labels will be missed if the range does not span an order of magnitude, so for cases such as:
cis plot temp_5:xglnwa.pm.k8dec-k9nov.col.tm.nc --type heatmap --logv
It can still be overidden with --vstep, e.g. for the above example --vstep 10 works well.
cis plot temp_5:xglnwa.pm.k8dec-k9nov.col.tm.nc --type heatmap --logv
