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