Hi Steven,
First let me say, your question is great. It is humble and great too.
Then, I would say, just do it. Sorry for the cliché, but
programming is a lot of trial and error. If you don't do, you will not make
errors, and you will not learn.
But lucky for you, you live in the age of

around the colorbar, the colorbar object has a member attribute called
outline which you can set_visible(False).
a = plt.colorbar()
a.outline.set_visible(False)
Should do the trick for that part.
I hope this helps!

Hi Eric,
Thanks for your reply. I've already suspected that it's a simple linear

And for better interpolation I should use griddata on a finer grid. That's

This is totally not somthing I can use, it looks horrible.

that are more generic to all plotting functions as well, but I

Instead I should have wrote

Hello,
I'm having troubles understand something about regression coefficients.
If I have two vectors:
x = [1.38, 1.98, 3.18, 3.56, 4.9, 6.21, 6.44, 7.47, 8.36, 8.81]
y = [8.19, 17.77, 20.12, 14.55, 20.17 ,31.22 ,28.94, 34.79, 40.26, 38.99]
and I would like to find out the regression coefficient
or a sequence of them.
Note that no extrapolation is done outside convex hull defined by input
data.

What I want to do plot is a cross section, and there is no easy way to
