developer workflow

I want to make a change to xarray.plot.plot.line and use that change, what is the best way of going about this? I was thinking that I could

(1) Fork xarrary on Github (2) Make a local clone of the fork (3) Edit the code for the function line in ‘plot/plot.py’

Then? I already use xarray that is installed with conda: conda install xarray .

Sorry need to ask because never done this before.

Hi, if you want to change something in xarray and use it instead of the original one you should uninstall it, and then install it in dev mode. From the xarray root directory:

pip install -e .

However, in that case this is probably not the best thing to do. Since the logic for xarray’s line plot is extremely simple, in that case you’d better make you’re own function out of it and call it instead. I.e. my_plot_func(dataarray) instead of datarray.plot().

Finally, you may want to consider using an accessor for this purpose. You will then be able to write something like:

datarray.qAp.plot()

Right, I forgot about https://github.com/pydata/xarray/pull/637 . I’ll see what I can do.
