Hi,
Please take a look at https://codepen.io/pen/JjjEvrO
If the error is smaller than point, which will frequently happen for long scales, then the error will be not visible at all. Errors are always shown over bars for barplot, is there any workaround for scatter?
edit:
The only solution I found is to show 2 similar traces, one with markers, 2nd with errors: https://codepen.io/DaanyWaay/pen/mddRKEb
