    <p>It is possible to use your own axes class. In your case you can inherit from <code>matplotlib.axes.Axes</code> and change the <code>drag_pan</code> method to always act as though the 'x' key is being pressed. However the zooming doesn't seem to be defined in that class. The following will only allow x axis panning:</p> <pre><code>import matplotlib import matplotlib.pyplot as plt class My_Axes(matplotlib.axes.Axes): name = "My_Axes" def drag_pan(self, button, key, x, y): matplotlib.axes.Axes.drag_pan(self, button, 'x', x, y) # pretend key=='x' matplotlib.projections.register_projection(My_Axes) figure = plt.figure() ax = figure.add_subplot(111, projection="My_Axes") ax.plot([0, 1, 2], [0, 1, 0]) plt.show() </code></pre> <p>For the zooming, you may have to look at the toolbar control itself. The <a href="https://github.com/matplotlib/matplotlib/blob/master/lib/matplotlib/backend_bases.py#L2953" rel="noreferrer">NavigationToolbar2</a> class has the <code>drag_zoom</code> method which seems to be what's relevant here, but tracking down how that works is quickly complicated by the fact that the different backends all have their own versions (e.g. <a href="https://github.com/matplotlib/matplotlib/blob/master/lib/matplotlib/backends/backend_tkagg.py#L789" rel="noreferrer">NavigationToolbar2TkAgg</a></p> <p><strong>edit</strong></p> <p>You <em>can</em> monkeypatch the desired behaviour in:</p> <pre><code>import types def press_zoom(self, event): event.key='x' matplotlib.backends.backend_tkagg.NavigationToolbar2TkAgg.press_zoom(self,event) figure.canvas.toolbar.press_zoom=types.MethodType(press_zoom, figure.canvas.toolbar) </code></pre> <p>You could do it properly and make a subclass of the toolbar, but you have to then create instances of Figure, FigureCanvas and your NavigationToolbar and put them in a Tk app or something. I don't think there's a really straightforward way to just use your own toolbar with the simple plotting interface.</p>

    1. COsweet! I'll have to try it. The part I was having trouble with was the subclassing + how to hook it into add_subplot.

    2. COthe "monkeypatch" approach almost worked, but somehow the assignment of the press_zoom method to individual instances doesn't stick (press zoom button, then unpress it, then press it again, now the zoom doesn't work). I got it to work by changing the __class__ method slot.

    3. COHmm that sounds pretty weird, it doesn't seem to unstick for me though I haven't tested it very comprehensively. And I see your alternative using `_zoom_mode`, probably much more sensible than changing `event.key`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
