BUG: plot_coord_time issues with longitude values over meridian #432

Description

BUG

Nightshade colours in a large swath when data is over the meridian. This generally only happens in select beams for a few radars so not super super major issue, but one to be aware of.
The plots for coord-time without the nightshade colouring should also be fixed like the plot_equatorward option fixed the same issue with latitude.

Remember to assess whether the plot type and options are appropriate for the data you are plotting, especially when plotting data over the poles in geographic or geomagnetic coordinates.

Priority

  • Minor - typo, incorrect naming, fails on specific uncommon situation
  • Major - misrepresentation of data, failure in a common situation
  • Urgent - failure in usage, large misrepresentation

Example of the bug

See Rems review for the last release for specific example: #428 (review)

Attempts

What have you tried already to fix it?
Minor fixes can be done by setting the ylim, e.g.: plt.ylim([-180,-100]) after the fact.
No fix for nightshade though.

Data Location

Effects RKN low and high numbered beams. Possibly some other polar radars.

Potential Solution(s)

Better handling of zmin and zmax in plot_coord_time().
Plotting restrictions on yaxis for lon, similar to plot_equatorward.
