How to save the plot to a numpy array in RGB format?

MatplotlibServer Side ProgrammingProgrammingNumpy

To save the plot to a numpy array in RGB format, we can take the following steps −

  • Create r, g and b random array using numpy.

  • Zip r, g and b (grom step 1) to make an rgb tuple list.

  • Convert rgb into a numpy array to plot it.

  • Plot the numpy array that is in rgb format.

  • Save the figure at the current location.

  • To display the figure, use the show() method.

Example

import numpy as np
from matplotlib import pyplot as plt
plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True
r = np.random.rand(100)
g = np.random.rand(100)
b = np.random.rand(100)
rgb = zip(r, g, b)
arr = np.array([item for item in rgb])
plt.plot(arr)
plt.savefig("myplot.png")
plt.show()
