Getting a BoxSelect without fitting the display to the selection?

[bgribble]

I would like to use a click and drag to select a region of the plot without zooming to fit the selection. A DragRect is basically what I want, but being able to initialize it with a button-2-click and drag.

It seems like the input maps only support pan or box-select as click actions, and I can't see a way in implot.cpp to disable the zoom-to-selection behavior when the mouse button goes up.

I'm using imgui/implot via the Python bindings, so modifying implot.cpp for my app is not really practical.

Is there a way to configure DragRect to do what I am looking for, or else to have a selection without zooming?

FWIW I have a workaround that has a 1-frame "glitch" but it's not that noticeable.

• Save the selection and axis limits each frame
• When the selection snaps back to "nothing selected", take the last-saved selection and use it to make a drag_rect
• On the next frame, reset the axis limits back to what they were before the selection snapped back

The behavior is that the selection instantly "converts" to a drag box when the button is released, and the limits of the plot stay the same (modulo the 1-frame glitch)
