Add colorbar that span multiple columns at a specified row in GridSpec #392
Description
Hey!
Not sure if this is my own lack of understanding or currently not possible. But I'm wondering if it is possible to add a colobar that spans multiple columns at a specific row in a grid? Using matplotlib we can do something like this
fig, axs = plt.subplots(nrows=2, ncols=2)
rng = np.random.default_rng()
data = rng.random((100, 100))
cm = axs[0, 0].pcolormesh(data)
fig.colorbar(cm, ax=axs[0, :], location="bottom")and get
while trying something similar in ultraplot
fig, axs = uplt.subplots(nrows=2, ncols=2)
rng = np.random.default_rng()
data = rng.random((100, 100))
cm = axs[0, 0].pcolormesh(data)
fig.colorbar(cm, ax=axs[0, :], location="bottom")gives
I think this would be helpful when sharing colormaps among columns, but not rows.

You are correct. I don't think we support that at this moment for inside axes colorbars. On the outside is possible, e.g.

Note span is not necessary as it defaults to the entire range

Found a fix for #393 but need to tool a bit for the other one, keep you posted @Holmgren825
