As this plugin is still in development, you can only install it from this repository. You will want to do the following steps:
$ git clone https://github.com/glue-viz/glue-solar.git
Then change directory to glue-solar and install with:
pip install -e .
This will auto-register the plugin with glue and install everything needed to run this plugin (including glue).
At the moment, this plugin provides a reader for solar data, you can give glue some solar data file in the FITS format. For example, you can start glue by using:
glue mydata.fits
and you can also load files from inside glue.
