调整 3D 散点图的大小

Question

我设法使用 Spyder (Python 3.5) 绘制了 3D 图形。但是，图形的大小太小了。如何增加图表的大小以便将其保存为图像文件？

下面是用于绘制图表的代码：

from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt



fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')

x =[0,1,2,3,4]
y =[11,1,5,2,9]
z =[1,2,3,4,5,6]



ax.scatter(x, y, z, c='r', marker='o')

ax.set_xlabel('Days since last interaction')
ax.set_ylabel('Number of conversions')
ax.set_zlabel('Total number of interactions')

plt.show()

谢谢！

您可以在创建图形时使用命名参数figsize

from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt

fig = plt.figure(figsize=(10, 10))
ax = fig.add_subplot(111, projection='3d')

x =[0, 1, 2, 3, 4, 0]
y =[11, 1, 5, 2, 9, 0]
z =[1, 2, 3, 4, 5, 6]  # this array contained one value too many. (I padded the other two arrays)

ax.scatter(x, y, z, c='r', marker='o')

ax.set_xlabel('Days since last interaction')
ax.set_ylabel('Number of conversions')
ax.set_zlabel('Total number of interactions')

plt.show()
