我正在使用以下代码在网格(x-y)数据上绘制z(二进制):
plt.scatter(x,y,z,color =' c',marker =' o')
结果很好。但我希望在相同的代码中增加标记大小。请帮助。

您可以使用s
关键字参数更改标记大小,如下所示:
plt.scatter(x,y,z, color='c', marker= 'o', s=100)
一个完整的例子:
import numpy as np, matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
#make some data similar to your description
a = np.linspace(0.,5.,10)
x,y = np.meshgrid(a,a)
z = np.random.randint(low=0,high=2,size=100).reshape(10,10)
#plot in 3D with s=100
fig = plt.figure()
ax = fig.add_subplot(111,projection='3d')
ax.scatter(x,y,z,marker='o',s=100)
#or plot in 2D and colour the points by z (sometimes easier to look at than 3d)
fig1,ax1 = plt.subplots()
ax1.scatter(x,y,c=z,marker='o',s=100,cmap="Blues")
这会产生以下图表:
