Hi,
Is there any way of setting hoverinfo property in plotly_express as done in plotly, as shown in https://plot.ly/python/hover-text-and-formatting/ ?
If no, is there any way of not showing the x value?
Thanks 
Jonathan
Plotly Express hover labels are configured using the hovertemplate attribute, which you can override on a per-trace basis. I’ll add more details in this related issue: https://github.com/plotly/plotly_express/issues/120
