Chart graphs with error streams in python

Question

for a while I tried to come up with a good way to graphically represent a series of data along with an estimated error.

Recently, I saw several graphs where the data was built as a line, and the background “tape” filled the area between the lines displaying data +/- sigma.

Is there a name for this type of graph, and is there any python toolkit capable of creating such graphs?

A simple way to fake it with matplotlib will also be useful - right now I just draw three lines, but I don't know how to fill the area between them.

Answer 1

I would use the fill_between method. Have a look at our favorite recipes in the matplotlib manual for some good examples. They have one that looks like this:

and another that looks like this:
