Question

我正在运行一个循环来绘制一堆不同的线，但最有意义的是将它们绘制在loglog图上（处理大约9个数量级）。他们用loglog绘图绘制它们应该如何绘制，但是只有当我尝试记录它们时，轴/轴标签才会消失。

#THIS IS FOR A NORMAL PLOT
import matplotlib.pyplot as plt

plt.figure()
for ii in list1:
    plt.plot(xarray[:], yarray[ii,:])
plt.show()

我尝试添加以下内容：

plt.xscale('log')

和

plt.yscale('log')

或者我试过

plt.loglog(xarray[:], yarray[ii,:])
plt.semilogy(xarray[:], yarray[ii,:])

任何帮助都会很棒，我对绘图的经验不多，但是我认为制作轴应该非常简单。感谢。

My plot without the axes

编辑：我也从traceback获得以下错误调用。我只是做了一个干净的重新安装matplotlib并仍然有相同的问题（它绘制但没有轴）

Answer 1

原来这个问题是由于出现同样问题造成的： In this Problem

我完全卸载了python，重新安装了python（适用于Mac OSX 10.3及更高版本的32位版本），matplotlib，scipy和numpy。现在轴正确绘制。

消失的轴，LogLog绘图Python
