matplotlib write text in the margin

If I make a graph using pylab from matlotlib like so...

import pylab as p
x = [0,1,2]
y = [2,4,6]
p.plot(x,y)
p.show()

I want to use the p.text function to add text to the graph. However, I want to put the text in the margin outside of the data window. The text function only accepts x,y coordinates that correspond to the data points rather than absolute x,y pixels coordinates of the entire window. Any idea how I can write text in the margins?

Solution

  • You can use the figtext function. Only note that the coordinates are 0-1, so something like the following places text to the left of the vertical axis:

    p.figtext(0.05, 0.5, 'foo')
