如何在pyqt/matplotlib导航中以编程方式选择平移/缩放 [英] How to programmatically select pan/zoom in pyqt/matplotlib navigation

问题描述

我有一个 pyqt4 matplotlib 应用程序，当应用程序打开时，我希望图形开始(默认)到平移缩放模式.我找不到文档中有关如何以编程方式执行此操作的任何示例或线索.

I have a pyqt4 matplotlib application and I would like the figure to start out (default) to the pan zoom mode when the application opens. I can't find any example or clue from the documentation on how to do this programmatically.

同样，我将如何在应用程序中启用快捷键(http://matplotlib.sourceforge.net/users/navigation_toolbar.html)

Also along this same line how would I enable the shortcut keys in my application (http://matplotlib.sourceforge.net/users/navigation_toolbar.html)

感谢您的任何建议.

推荐答案

我遇到了类似的问题，在我的情况下，我使用 toolbar.zoom() 解决了它:

I had a similar issue and in my case I solved it by using toolbar.zoom():

import pylab

plt.Figure()
thismanager = get_current_fig_manager()
thismanager.toolbar.zoom()

在这种情况下，图形将与已选择的缩放工具一起出现

In that case the figure will appear with the zoom tool already selected
