Oct 20, 2014 · The idea is to convert the angle of a vector to the color using HSV colors Hue value. The absolute value of the vector is used as the saturation and the value.

If you want to set colors directly, use color instead. The size of C must match the number of arrow locations. angles {'uv', 'xy'} or array-like, default: 'uv'
