yAxis display having floating point error

If you have tiny percents, and want tickformat to be a percent, plotly has problems calculating the display values:

Is there an alternate format that might work better? I tried ‘%’ and that just made everything ‘0%’.

Any help would be great; thank you!

Beautiful! Thank you for your help! I need to get a better grasp on those formatting codes.

Yes, I’ve looked at that and my eyes glaze over. I need to spend some time studying it
