Hide Axis, Borders and White Spaces in Matplotlib

  1. Hide the Axis in Matplotlib Figure
  2. Hide the Whitespaces and Borders in Matplotlib Figure

This tutorial explains how to hide the axis in the plot using the matplotlib.pyplot.axis('off') command and how to remove all the whitespaces, and borders in the figure while saving the figure.

Hide the Axis in Matplotlib Figure

To hide the axis, we can use the command matplotlib.pyplot.axis('off').

import numpy as np
import matplotlib.pyplot as plt 

img = np.random.randn(10,10)
plt.imshow(img)
plt.axis('off')

plt.show()

Output:

Hide the axis in Matplotlib Figure

It hides both the X-axis and Y-axis in the figure.

If we just want to turn either the X-axis or Y-axis off, we can use axes.get_xaxis().set_visible() or axes.get_xaxis().set_visible() method respectively.

import numpy as np
import matplotlib.pyplot as plt 

img = np.random.randn(10,10)

fig=plt.imshow(img)
ax=plt.gca()
ax.get_xaxis().set_visible(False)

plt.show()

Output:

Hide the X-axis only in Matplotlib Figure

It only hides the X-axis in the figure.

Hide the Whitespaces and Borders in Matplotlib Figure

The plt.axis('off') command hides the axis, but we get whitespaces around the image’s border while saving it. To get rid of whitespace around the border, we can set bbox_inches='tight' in the savefig() method. Similarly, to remove the white border around the image while we set pad_inches = 0 in the savefig() method.

import numpy as np
import matplotlib.pyplot as plt 

img = np.random.randn(10,10)

fig=plt.imshow(img)
plt.axis('off')
plt.savefig('image.png', bbox_inches='tight',pad_inches = 0)

Saved Image:

Hide the whitespaces and borders in Matplotlib Figure

It saves the images without any axis, borders, and whitespaces using the savefig() method.

We can also save the image without axis, borders, and whitespace using the matplotlib.pyplot.imsave() method.

import numpy as np
import matplotlib.pyplot as plt 

img = np.random.randn(100,100)
plt.imsave("kapal.png",img)
