NaN appearing in Hoverdata

1

I noticed some strange behavior when plotting data with error bars along with data not containing error bars.

Plotly appears to add “NaN” where no error data is provided or the error data is 0

Not a big issue really but I thought I would mention it

The data I’m plotting is

Thanks very much.

Looks like the problem is that our hover text labels tried to convert log(0) to text which leads to NaNs.
