This is probably getting a bit off-topic now, maybe better keep this

Hi,
I'm not sure this is entirely on-topic as it relates to the matplotlib
sphinx extension. I hope it's still acceptable!
I am writing some documentation using sphinx, and I would like to refer

and it gets imported fine ju

Hi!

I have a rather complex basemap-derived plot that I want to save as

In essence, it uses the blumarble() to add a nice background, plots some
stuff on top of that, and als

You can just use the bins keyword to plt.hist (or np.hist):

Hi,
We are trying to plot a climogram (where you have temperature on the
left hand axis, and precipitation on the RHS). The data need to be
properly scaled as well. We have used twinx() to get the two axes.
However, the precipitation (plotted as bars) goes over the temperature
line, when it should

Mmmm, this is OK, let's say I wanted a figure with a transparent

Hi,
Some colleagues have sent some plots which they generated using IDL

I have two datasets with different data coordinates, which I want to plot on

Initially, I just want one plot to follow
