I want to plot data, then create a new figure and plot data2, and finally come back to the original plot and plot data3, kinda like this: import numpy as np import matplotlib as plt x = arange(5) y = np.exp(5) plt.figure() plt.plot(x, y) z = np.sin(x) plt.figure() plt.plot(x, z) w = np.cos(x) plt.figure(“””first figure”””) … Read more
I am trying to save plots I make using matplotlib; however, the images are saving blank. Here is my code: plt.subplot(121) plt.imshow(dataStack, cmap=mpl.cm.bone) plt.subplot(122) y = copy.deepcopy(tumorStack) y = np.ma.masked_where(y == 0, y) plt.imshow(dataStack, cmap=mpl.cm.bone) plt.imshow(y, cmap=mpl.cm.jet_r, interpolation=’nearest’) if T0 is not None: plt.subplot(123) plt.imshow(T0, cmap=mpl.cm.bone) #plt.subplot(124) #Autozoom #else: #plt.subplot(124) #Autozoom plt.show() plt.draw() plt.savefig(‘tessstttyyy.png’, dpi=100) … Read more
I need to add two subplots to a figure. One subplot needs to be about three times as wide as the second (same height). I accomplished this using GridSpec and the colspan argument but I would like to do this using figure so I can save to PDF. I can adjust the first figure using … Read more
Sometimes I come across code such as this: import matplotlib.pyplot as plt x = [1, 2, 3, 4, 5] y = [1, 4, 9, 16, 25] fig = plt.figure() fig.add_subplot(111) plt.scatter(x, y) plt.show() Which produces: I’ve been reading the documentation like crazy but I can’t find an explanation for the 111. sometimes I see a … Read more
