Display correlation coefficient on the upper panel.

[tellyshia]

Hi @garthtarr ,
I like the interactive part very much. I wish I could display correlation coefficient on the upper panel since the information on both panels are rather redundant. Have you thought of that before?

Hi, yes it's a good idea. However, it's not a priority for me to implement at this stage (happy to take pull requests).

As an alternative, you might consider using GGally::ggpairs() in conjunction with plotly::ggplotly(). For example:

# install.packages("GGally")
# install.packages("plotly")
library(GGally)
data(tips, package = "reshape")
pm <- ggpairs(tips, columns = c(1, 2, 7)) + theme_bw()
pm
ggplotly(pm)
