matplotlib scatter fails with error: 'c' argument has n elements, which is not acceptable for use with 'x' with size n, 'y' with size n

Question

I am trying to create a scatter plot using matplotlib where each point has a specific color value.

Answer 1

Convert colors to a float array with 0 <= colors <= 1 and it should work fine.

sc.scatter(np.arange(len(values)), values, c = colors/255)
