[Matplotlib-users] Using bbox_to_anchor to get the legend off of my graph

Hi, I am graphing several time series together on the same graph, and so it is important to have a legend. I am also stacking two graphs on top of one another, because some of the data is of a different type. I wrote the graphing code as follows (pardon the newbie code, this is my first

Hey there, I'm trying to plot a bunch-o-vectors, colored red or blue, depending on whether their magnitude is positive or negative (they represent stresses), and I'm doing something like this: mag1 = evals[:,0] ex1 = evecs[:,0,1] ey1 = evecs[:,0,0] C1 = np.where(mag1 >= 0, 'red', 'blue') mag2
