[英]Combine Matplotlib with PyQt4
我有一个简单的GUI程序,当我单击button
,它将从txt
文件进行子图matplotlib处理,并将图像另存为png
文件,但是即使处理成功,我也遇到了此错误。
我尝试使用canvas
, figure
但仍然出现错误,说实话,我不太了解如何结合使用matplotlib和pyqt。
这是我的代码

您不应该在与主线程不同的线程中绘图,发送信号指示处理已完成,除了使用matplotlib之外,您还必须指示后端qt4,您可以将绘图作为小部件的一部分插入,如下所示:
要清除上一个窗口,您必须使用cla()
函数:

如果要显示图,则应使用以下代码:
