如何在 matplot python 中绘制单个点 [英] How can I plot a single point in matplot python

问题描述

我想在我的图表上绘制一个点但似乎它们都需要按照列表或方程式进行绘制.

I'd like to plot a single point on my graph but it seems like they all need to plot as either a list or equation.

我需要像ax.plot(x，y)一样进行绘制，并且点将出现在我的图的x，y坐标上.

I need to plot like ax.plot(x, y) and a dot will be appeared at my x, y coordinates on my graph.

这是我的代码

import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import host_subplot
import mpl_toolkits.axisartist as AA
import numpy
fig = plt.figure()
plt.xlabel('Width')
plt.ylabel('Height')
ax = fig.gca()
ax.set_xticks(numpy.arange(0,grid[0] + 20,20))
ax.set_yticks(numpy.arange(0,grid[1] + 20,20))
ax.plot(105, 200)
plt.grid()
plt.show()

推荐答案

这对我有用:

plt.plot(105,200,'ro')
