Add support for captions and subtitles

[geponce]

This example shows the difference between ggplot and ggplotly objects regarding the use of "labs". Source: R for Data Science

library(ggplot2)
library(plotly)
p<-ggplot(mpg, aes(displ, hwy)) +
  geom_point(aes(color = class)) +
  geom_smooth(se = FALSE) +
  labs(
    title = "Fuel efficiency generally decreases with engine size",
    subtitle = "Two seaters (sports cars) are an exception because of their light weight",
    caption = "Data from fueleconomy.gov"
  );
p  # This is ok, a ggplot2 object
g <- ggplotly(p)
g  #  "labs()" Just showing title (centered) and  subtilte & caption are not even showing up

labs() OK

labs() not ok

Thank you all, implementing this enhancement would be very much appreciated. Having important info about a chart (subtitles and captions) flow through to ggplotly is likely very important to most users.

This would be a major win if implemented @cpsievert :) 💯

+1 for implementing this

[kenahoo]

Just noticed this behavior too - would be great to get this working.

Yep, that would be great.

Would love this functionality. Anything that keeps the ggplot -> plotly conversion as consistent as possible is a plus IMO.

I'm following this more closely than my local ballot measure tbh
