如何绘制一个点而不用 matplotlib.pyplot.plot 填充它？

Question

Both plt.scatter and plt.plot can draw dots

this code draws a dot without filling it

plt.scatter(1, 1, s=80, facecolors='none', edgecolors='r')

while plt.plot doesn't seem to support facecolors property

plt.plot(1,1,'ro')

how do I draw a dot without filling it with plt.plot?

Answer 1

For regular plots, you can use markerfacecolor :

plt.plot(1, 1, 'ro', markerfacecolor='none')
