Is your feature request related to a problem? Please describe.
I love how efficiently we can plot line data for different observations using xr.DataArray.plot(hue={hue coordinate name})
over a 2D array, and I have appreciated xr.DataArray.plot.step()
for plotting histogram data using interval coordinates. Today, I wanted to plot/compare several histograms over the same set of bins. I figured I could write xr.DataArray.plot.step(hue={...})
, but I found out that this functionality is not implemented.
Describe the solution you'd like
I think we should have a hue kwarg for xr.DataArray.plot.step()
. When specified, we would be able to plot 2D data in the same way as xr.DataArray.plot()
, except that we get a set of step plots instead of a set of line plots.
Describe alternatives you've considered
- Use
xr.DataArray.plot()
instead. This is effective for histograms with many bins, but inaccurately represents histograms with coarse bins - Manually call
xr.DataArray.plot.hist()
on each 1D subarray for each label on the hue coordinate, adding appropriate labels and legend. This is fine and my current solution, but I think it would be excellent to use the same shorthand that was developed for line plots.
Additional context
I didn't evaluate the other plotting functions implemented, but I suspect that others could appropriately consider a hue argument but do not yet support doing so.
