Drawing rectangle with border only in matplotlib

Question

So I found the following code here:

from matplotlib import pyplot as plt from matplotlib.patches import Rectangle someX, someY = 0.5, 0.5 plt.figure() currentAxis = plt.gca() currentAxis.add_patch(Rectangle((someX - .1, someY - .1), 0.2, 0.2,alpha=1)) plt.show() 

Which gives:

But what I want is a rectangle with only a blue border and inside of it to be transparent. How can I do this?

Answer 1

You just need to set the facecolor to the string 'none' (not the python None)

from matplotlib import pyplot as plt from matplotlib.patches import Rectangle someX, someY = 0.5, 0.5 fig,ax = plt.subplots() currentAxis = plt.gca() currentAxis.add_patch(Rectangle((someX - 0.1, someY - 0.1), 0.2, 0.2,                       alpha=1, facecolor='none'))
