python的scatter中color为什么不能设置每个点的颜色

Answer 1

下面是文档中对scatter的参数c的说明：
c : color, sequence, or sequence of color, optional, default: ‘b’
c can be a single color format string, or a sequence of color specifications of length N, or a sequence of N numbers to be mapped to colors using the cmap and norm specified via kwargs (see below). Note that c should not be a single numeric RGB or RGBA sequence because that is indistinguishable from an array of values to be colormapped. c can be a 2-D array in which the rows are RGB or RGBA, however, including the case of a single row to specify the same color for all points.
可见可以传入一个序列（list之类的）
