Jul 28, 2020 · According to here, when zorder is used with alpha, the colors are updated as follows: RGB = RGBold * (1 - alpha) + RGBnew * alpha where RGBnew is whichever color has higher zorder, and RGBold is the one with lower zorder, and alpha belongs to RGBnew.

The alpha value of a color specifies its transparency, where 0 is fully transparent and 1 is fully opaque. When a color is semi-transparent, the background color will show through. The alpha value determines the resulting color by blending the foreground color with the background color according to the formula

I'm wondering if it is possible to have individual alpha values for each point to be plotted using the scatter function of Matplotlib. I need to plot a set of points, each one with its alpha value.
