I’m trying to create a plot that shows a trace of temperature data and would like the left axis to be in degrees Celsius and the right y-axis to be in degrees Fahrenheit. I found this post, Multiple axis for one trace, which has an answer that involves making two separate traces. I’m wondering if it is possible in plotly.js to provide some conversion function or even relayout with updated range or even explicit ticktext/tickvals so I can have one trace with two “linked” y-axes?
My only concern with multiple traces is any future performance problems having twice the amount of data. I’m guessing that plotly has to draw it twice too.
Any guidance is appreciated.
