I'm having some trouble trying to change the figure size when using plt.subplots. With the following code, I just get the standard size graph with all my subplots bunched in (there's ~100) and obviously just an extra empty figuresize . I've tried using tight_layout, but to no avail.
def plot(reader): channels=[] for i in reader: channels.append(i) plt.figure(figsize=(50,100)) fig, ax = plt.subplots(len(channels), sharex=True) plot=0 for j in reader: ax[plot].plot(reader["%s" % j]) plot=plot+1 plt.tight_layout() plt.show()any help would be great!

You can remove your initial plt.figure(). When calling plt.subplots() a new figure is created, so you first call doesn't do anything.
The subplots command in the background will call plt.figure() for you, and any keywords will be passed along. So just add the figsize keyword to the subplots() command:
def plot(reader): channels=[] for i in reader: channels.append(i) fig, ax = plt.subplots(len(channels), sharex=True, figsize=(50,100)) plot=0 for j in reader: ax[plot].plot(reader["%s" % j]) plot=plot+1 plt.tight_layout() plt.show()
