Set size of subplot in matplotlib

72,149

Just switch figure size width and height from:

fig = plt.figure(figsize=(20, 8))

to:

fig = plt.figure(figsize=(8, 20))

to use the whole page for your plots.

This will change your plot from:

    I wonder how to set the size of the subplot when figure contains multiple subplots (5 × 2 in my case). No matter how big I allow the whole figure to be, the subplots always seem to be small. I would like to have direct control of the size of the subplot in this figure. The simplified version of the code is pasted below.

    import numpy as np
    import matplotlib.pyplot as plt
    
    x = np.random.randn(20)
    y = np.random.randn(20)
    
    fig = plt.figure(figsize=(20, 8))
    
    for i in range(0,10):
        ax = fig.add_subplot(5, 2, i+1)
        plt.plot(x, y, 'o')
        ax.xaxis.set_visible(False)
        ax.yaxis.set_visible(False)
        # x and y axis should be equal length
        x0,x1 = ax.get_xlim()
        y0,y1 = ax.get_ylim()
        ax.set_aspect(abs(x1-x0)/abs(y1-y0))
    
    plt.show()
    fig.savefig('plot.pdf', bbox_inches='tight')

      Try to set square figure size, i.e. figsize=(20,20). You aspect ratio set almost square subplots but figure is not.
