Variables Dimensions Panel Enhancements

doutriaux1 commented 6 years ago

As discussed at recent meeting we can improve the dimensions selection panel by

Adding Units information next to the stride box except for time dimensions where the units are not necessary since values are converted to actual date (in case conversion failed though we should print the units)
In case dimension as a modulo add half a modulo before and after the default selected values for this variables. The reason for this (here using longitudes)
- If data is from 0-360, then user can plot -180, 180
- In case of polar plots, user needs an extra longitude to "close" the gap, e.g. lon goes -180 to 175, we have a small gap, but selecting -180 to 180 the gap disappear.

I'm adding a picture to try to explain this as well: vcdatdims

Code to get the modulo in cdms

import cdms2, cdat_info, os
f = cdms2.open(os.path.join(cdat_info.get_sampledata_path(),"clt.nc"))
s = f["clt"]
modulo = s.getLongitude().getModulo()

Also the sliders should not say S and E but maybe be replaced with [ and ]

I made a PR here: https://github.com/CDAT/vcs-js/pull/46 to help implement this.

When that is reviewed and accepted I will make a PR from this branch: https://github.com/James-Crean/vcdat/tree/units_on_axes
