Question

是否可以从纯文本控制台运行matplotlib？我使用matplotlib生成少量图表并使用fig.savefig()保存。因此，基本上，图形在后台生成并保存在文件系统中。

错误是

    self.fig1 = plt.figure(figsize=plt.figaspect(aspect_ratio))
  File "/usr/local/lib/python2.7/dist-packages/matplotlib/pyplot.py", line 535, in figure
    **kwargs)
  File "/usr/local/lib/python2.7/dist-packages/matplotlib/backends/backend_tkagg.py", line 81, in new_figure_manager
    return new_figure_manager_given_figure(num, figure)
  File "/usr/local/lib/python2.7/dist-packages/matplotlib/backends/backend_tkagg.py", line 89, in new_figure_manager_given_figure
    window = Tk.Tk()
  File "/usr/lib/python2.7/lib-tk/Tkinter.py", line 1818, in __init__
    self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use)
_tkinter.TclError: no display name and no $DISPLAY environment variable

从终端运行matplotlib以生成和保存数字
