Add a vertical line in plotly

ggplot2
shiny
shinydashboard
plotly

#1

I would like to add a vertical line to my chart corresponding to the mean, median or standard deviation using plotly. I was able to do it with ggplot2 and then transformed it to plotly with ggplotly but didn't work as I expected. Anyone knows how to do it with just plotly?

From plotly's API, the function I think you want is add_segments()

If you check Carson's plotly book, there's a section where he talks about how you can extend ggplotly() to accomplish this--just scroll down a bit and you'll see a section where ggplotly() pipes into an add_function() call where you can use add_segments()--hope that helps!

edit: I think that it's worth the time to learn how plotly's API works--it can be really rewarding!

Thank you so much! I'm going to try this.
Yes, my real problem is that I don't know how this API really works :confused: but I'm certainly going to take some time and study how plotly works =)

It can be really intimidating; so don't worry! You got this!
