There is probably a simple answer to this, but I don't see it. How can
I pad the axis limits automatically? For instance, in the below
example, the x axis limits are the data points and the y limit is
close. I want to have a function that pads the axis limit at least, by
say, 10% of the range of x past the last data point without having to
take my x values and calculate some sensible x limit. Is this
possible?
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(111)
x = [1,2,3]
y = [8125, 9754, 10855]
ax.plot(x,y,marker='D',ms=12)
plt.show()
A similar issue came up recently on the list:
http://old.nabble.com/Why-are-bars,-errorbars…-clipped-td33525497.html
I posted a snippet of code there. Ben Root also mentioned padx and pady parameters, but I was not able to find them.

Does the margins() function or method do what you want?

Thanks for the tip, Eric. I’m continually surprised by all the useful stuff that’s nestled in the corners of matplotlib.
Hmm, it looks like margins doesn’t support log scales, though. Maybe I’ll submit a PR on this later.
Best,

Indeed. Both solutions are nice. I've never noticed margins before,
even though this is a common issue for me. The documentation isn't all
the clear, what exactly to do with it, but set_xmargin and set_ymargin
cleared that up. Thanks.
