It sounds like you were using the right approach, you just got a bit lost on what some of the keyword parameters to annotate, etc do. Here's an example that should do what you want: import matplotlib.pyplot as plt from matplotlib.ticker import MultipleLocator fig, ax = plt.subplots() # Set the

Hi all I'm a new user to matplotlib, and I'm having a little difficulty with something I feel must be basic. When I plot our data, I'm using a canvas that is 4"x4" at 128 DPI and saving the canvas as a png. Here's the basics of the code: imageWidth = 4 imageHeight = 4 DPI = 128

Hi Nico, If you're using IPython then you can do a cool trick. Say your your instantiation is called var. You can type: var? and it'll spit out some info about the object, including what it's an instance of. If you type var?? it'll try to print out more detailed information. Hope that helps
