标记颜色。可能的值：
请注意，c不应该是单个数字RGB或RGBA序列，因为它与要进行颜色映射的值数组无法区分。如果要为所有点指定相同的RGB或RGBA值，请使用具有单行的二维数组。否则，在大小与x 和y匹配的情况下，值匹配将具有优先权。
默认为None。在这种情况下，标记的颜色是由的值来确定color，facecolor或facecolors。如果未指定或None标记颜色，则标记颜色由Axes“当前”形状的下一个颜色确定并填充“颜色循环”。此周期默认为rcParams["axes.prop_cycle"]。
ax.scatter(X1,X1,c=b)
ax.scatter(X2,X2,c=b,s=50)
ax.scatter(X1,X1,c=g)
