How to increase the size of my plot using plt.subplot

Question

I am using colab notebook for generating some numbers using autoencoders. I am able to generate the numbers successfully but it is really small and invisible. I am using matplotlib for data viz.

Here is my plot_image function:

  def plot_image(image, shape=[28,28]):
     plt.imshow(image.reshape(shape), cmap="Greys", interpolation="nearest")
     plt.axis("off")

Here is my code for visualizing the numbers:

  for iteration in range(n_digits):
     plt.subplot(n_digits, 10, iteration+1)
     plot_image(outputs_val[iteration])

I am also using matplotlib inline function as:

%matplotlib inline

Can anyone guide me to visualize my result with a bigger plot? I am attaching the screenshot of my generated result.Thanks in advance guys.

Sometimes my plots are small when I call plt.show() but then I can resize the window and it grows with it. Would that be applicable with %matplotlib inline? Or maybe instead of a 10 X 1 you could make a 5 X 2 or 3 X 3 and omit the last graph? Here is their documentation: matplotlib.org/api/_as_gen/… It tells you all the methods available to you, as well as some examples at the bottom you can look through! — Reedinationer

You can increase the figure size by use the figure command. See below

def plot_image(image, shape=[28,28]):
    fig = plt.figure(figsize=(18, 18)) # set the height and width in inches
    plt.imshow(image.reshape(shape), cmap="Greys", interpolation="nearest")
    plt.axis("off")
    plt.show()
