绘制 3d 图形时的问题

Question

我正在尝试 plot 和 3d 图形代码运行正常，但 plot 附加了空快照。 我还共享了图形数据 csv 文件https://drive.google.com/file/d/1dohDHX7mJKliF8X2xowCqRURQOuQE0Ip/view?usp=sharing .

data = np.genfromtxt("graph-data.csv", delimiter=",", names=["x", "y","z"])
x, y, z = zip(*data)
fig = plt.figure()
ax = plt.axes(projection='3d')
ax.set_xlabel('CPU availability(%)')
ax.set_ylabel('Memory availability(%)')
ax.set_zlabel('Frame Drop Rate(%)')
ax.plot_surface(np.array(x).reshape(712,1), np.array(y).reshape(712,1), np.array(z).reshape(712,1), 
cmap='viridis', edgecolor='none')
#ax.plot_surface(x, y, z,cmap='viridis', edgecolor='none')
plt.show()

提前致谢

你可以使用trisurf ，你的代码变成（注意我删除了reshape功能）

data = np.genfromtxt("graph-data.csv", delimiter=",", names=["x", "y","z"])
x, y, z = zip(*data)
fig = plt.figure()
ax = plt.axes(projection='3d')
ax.set_xlabel('CPU availability(%)')
ax.set_ylabel('Memory availability(%)')
ax.set_zlabel('Frame Drop Rate(%)')
ax.plot_trisurf(np.array(x), np.array(y), np.array(z), cmap='viridis', edgecolor='none')
plt.show()
