Define different subplot titles

I have a couple of time series charts. See example here:

The first one shows the values for different locations. The second one is the average at different time point. matplotlib has the API to set the subplot and the title. Is there a way to set the chart title for the second one using plotly.js?

Thanks.

Not at the moment, you can subscribe to https://github.com/plotly/plotly.js/issues/2746 for the most up-to-date development info.

Iā€™d recommend using paper-referenced annotations

in the meantime.
