How to use Matplotlib in Django?
You need to remove the num
parameter from the figure constructor and close the figure when you're done with it.
import matplotlib.pyplotdef test_matplotlib(request): f = figure(figsize=(6,6)) .... matplotlib.pyplot.close(f)
By removing the num
parameter, you'll avoid using the same figure at the same time. This could happen if 2 browsers request the image at the same time. If this is not an issue, another possible solution is to use the clear method, i.e. f.clear()
.
1.save picture which created by matplotlib
for example:plt.savefig('./app1/static/visualize.png') 2.use the picture in your html codefor example:
