When the mouse scrolls, how to ensure that the range of the y-axis and the range of the x-axis remain at a fixed scale.

When the mouse scrolls, how to ensure that the r ange of the y-axis and the range of the x-axis remain at a fixed scale.

It's not currently possible. Each axis will independently zoom by 10% of its own range.

We could introduce an ImPlotFlags_Equal that would constrain each axis to have the same units/pixel ratio. Would that solve the issue you are having?

@epezent This feature would be extremely useful. Locking the aspect ratio between the x- and y-axes is a staple feature of most plotting frameworks.

[epezent]

Roger that. I'm looking into it.

This would be very useful to me if made available in Dear PyGUI (related issue: hoffstadt/DearPyGui#305).

[epezent]

I have this mostly working, but in the process I've made several changes to to how axes are handled in general. So it's taking a bit longer than expected. Hope to merge soon.

This work has been completed and merged to master. Enabled with ImPotFlags_Equal. It only constrains the primary x and y axes; auxiliary y axes are ignored.

Please review and post back if you find issues. It ended up being a bit more nuanced than I anticipated, so there may be a chance I missed an edge case.

i think his problem not this,he want x or y axis could be lock，or lock range （ scale factor?）

i think problem is scale factor? Enabled with ImPotFlags_Equal cant fix
