PROPER WAY TO USE MATPLOTLIB:
In summary: matplotlib is easy to use in a way that has global state, but that will break in a threading application. Using the Figure() API is safe. Thus:
from matplotlib.backends.backend_agg import FigureCanvasAgg as FigureCanvas from matplotlib.figure import Figure fig = Figure() canvas = FigureCanvas(fig) ax = fig.add_subplot(111) ax.plot([1, 2, 3]) ax.set_title('hi mom') ax.grid(True) ax.set_xlabel('time') ax.set_ylabel('volts') canvas.print_figure('test')
