I have created an array thusly:
import numpy as np
data = np.zeros( (512,512,3), dtype=np.uint8)
data[256,256] = [255,0,0]
What I want this to do is display a single red dot in the center of a 512x512 image. (At least to begin with... I think I can figure out the rest from there)
The following should work:
from matplotlib import pyplot as plt
plt.imshow(data, interpolation='nearest')
plt.show()
If you are using Jupyter notebook/lab, use this inline command before importing matplotlib:
%matplotlib inline
