Disable Diagonal Selection on cartesian zoombox drag

Hi Team Plotly,

I would like to enable the horizontal and vertical axis selection on bar/line charts, but I want to disable the diagonal selection – i.e. I don’t want to user to simultaneously select both axis, but only one at a time.

I have tried different solutions, but I could not get the desired effect. For example, setting fixedrange:true, disables either vertical or horizontal selection. But, I want to disable only diagonal selection, and keep both horizontal and vertical selections enabled.

Is it possible to have this feature for diagonal selection, like diagonalFixedRange:true? or have a flag to disable just the diagonal selection?

I'm using this library in ReactJS, the Plotly.js update will also ReactJS package?

Thank you very much for you help and the wonderful library 😊.

Start by reproducing the issue with bar and line charts using cartesian zoombox drag, comparing horizontal, vertical, and diagonal selections. Review how fixedrange currently affects axis selection and determine the existing entry point for zoombox selection. Done means horizontal and vertical selection remain available while simultaneous diagonal selection can be disabled, with the behavior usable through the ReactJS package.
