Deprecation warning: Use Matplotlib to load the colormaps

[Jonathan Slavin]

Hi,

I just updated to the latest version of sunpy and now plotting maps for Hinode XRT I get:

SunpyDeprecationWarning: Use Matplotlib to load the colormaps

  self.plot_settings['cmap'] = cm.get_cmap(name='hinodexrt')

This is odd since all I'm doing is:

m = sunpy.map.Map(file)

m.plot()

show()

In fact the warning is shown as soon as load the file.

Ah, found it.  It seems that in sunpy/map/sources/hinode.py the line

        self.plot_settings['cmap'] = cm.get_cmap(name='hinodexrt')

needs to be replaced with

        self.plot_settings['cmap'] = plt.get_cmap(name='hinodexrt')

(with "import matplotlib.pyplot as plt" added to the file as well).

Hi Jon,

Thanks for the bug report, it looks like we missed some of the old code when we deprecated that function. I have opened a bug on our tracker https://github.com/sunpy/sunpy/issues/2616 and we will fix it for the next bug fix.

Stuart
