[bug] wrong range values for boxplot of layout type category

When I inspect the range returned after the ‘plotly_selected’ callback in a boxplot with a categorical axis. I get the string values which is fine

But, if I want to get the pixel values or better yet the range that the selection translates to, I get strange results.

I tried d2p and d2c (c2p and c2r didnt produce any results) and the results dont seem right. I believe there is a bug here unless I’m wrong

See the screen shot below

any chance there’s documentation for these conversions anywhere?

Good question, @etpinard ? The only place I’m aware of is buried deep in the code:

https://github.com/plotly/plotly.js/blob/e26f8f4c9c75a0381e75dd4a56035f7fbf07fe73/src/plots/cartesian/set_convert.js#L40-L55

That describes what the letters d/c/l/p/r mean, so you can extrapolate to the x2y functions. Perhaps we were trying to keep our options open, thinking if we don’t document these functions we can change them without considering it a breaking change? 🙈 But obviously people like yourself have found them and depend on them so at this point we really should document them publicly.

Or include px values as part of the event data.

and the range values (of the selection box) too?
