[Feature Request] Show errors as absolute values

[Batalex]

Hi,

Errors in Plotly are shown upon hover as relative values. For example, in the following graph

data = {
    "type": "scatter",
    "y": [10, 11],
    "error_y": {
        "type": "data",
        "array": [1, 2],
        "arrayminus": [1, 2]
    }
}

the first data point is displayed as 10 +1 /-1.

It would be interesting for some cases to display the absolute values as an interval 10 (9, 11). For example when plotting odds ratios it is preferable to read the confidence interval in a straightforward way rather than showing the spread. Even with hovertemplate I could not figure out how to properly set this behavior.

I think it could implemented with a new "display" key in error_x|error_y with the values "relative" (default) or "absolute"

Hi - we are currently trying to tidy up Plotly's public repositories to help us focus our efforts on things that will help users most. Since this issue has been sitting for several years, I'm going to close it. If it's still a concern, we'd be grateful if you could open a new issue (with a short reproducible example if appropriate) so that we can add it to our backlog. Thanks for your help - @gvwilson
