*) Error due Scatter () due to irregularities in the parameter

Marker Color. Possible values:

Monochrome format string.
A series of color specifications of length n.
Use cmap and norm mapped to the sequence of n digital color .
A two-dimensional array, where the line is RGB or RGBA.

Note, C should not be a single sequence of digital RGB or RGBA, because it can not distinguish between the color array of values to be mapped. To specify the same value for all RGB or RGBA point, a two-dimensional array having a single row. Otherwise, the size of x and y case of a match, the matching value will take precedence .

The default is None. In this case, the color of the marker is determined by the valuecolor , facecoloror facecolors. If not specified orNone marker color, the color of the mark Axes"current" shape at a determined color and fill "color cycle." This is the default cyclercParams["axes.prop_cycle"] .

        ax.scatter(X1,X1,c=b)
        ax.scatter(X2,X2,c=b,s=50)
        ax.scatter(X1,X1,c=g)
