set customized cmap lisa_cluste()

[stevenlis]

I came across the following problem:

https://gis.stackexchange.com/questions/329433/how-to-fix-colors-of-lisa-cluster-maps-from-pysal

I tried to set another colormap, such as

fig, ax = lisa_cluster(moran_loc, gdf, cmap='Blues')

TypeError: plot() got multiple values for keyword argument 'cmap'

splot/splot/_viz_esda_mpl.py

Lines 921 to 932 in 11da787

	hmap = colors.ListedColormap(colors5)
	if ax is None:
	figsize = kwargs.pop('figsize', None)
	fig, ax = plt.subplots(1, figsize=figsize)
	else:
	fig = ax.get_figure()
	gdf.assign(cl=labels).plot(column='cl', categorical=True,
	k=2, cmap=hmap, linewidth=0.1, ax=ax,
	edgecolor='white', legend=legend,
	legend_kwds=legend_kwds, **kwargs)

@StevenLi-DS, thank you for the issue! We currently do not support the change of a cmap in lisa_cluster(). But I will have a look at it for a future release.

If you are interested in changing the colours and need a quick fix, I would recommend cloning the splot GitHub repo, installing splot from your local copy (e.g. installing splot as a developer with cd splot, pip install . in your chosen Conda environment) and changing the colours in: def mask_local_auto(moran_loc, p=0.5): found in _viz_utils.py.

There is a little bit of information on how to install splot for development here and I am happy to add some more in the coming weeks.

Same problem. I think it's important and easily do it by dectect whether the cmap params passed
