Translate plotmath expressions #571
Description
I have 2 issues using function ggplotly in R:
Question 1 What are the ways to keep R plotmath expressions while converting ggplot2 plots to plotly format using function ggplotly?
Now the expressions are converted to [object Object] as in this example below:
library(ggplot2)
library(plotly)
qplot(mpg, wt, data = mtcars) +
ggtitle(expression(bar(x) == sum(frac(x[i], n), i==1, n)))
ggplotly()
Question 2
How to get rid of double labels in the legend of plotly graph and make them look like in ggplot2 graph? I.e. how to get 6 in stead of (6,6):
qplot(mpg, wt, data = mtcars, colour = as.factor(cyl), fill = as.factor(cyl))
ggplotly()

plotmath expressions aren't yet possible. #375 will have to be fixed first.
For question 2, at least in this example, you could avoid the redundant mapping

Perhaps
simsalapar::expr2latex(), or it's source, would be useful herecpsievert commentedon May 16, 2019
Can maybe borrow ideas from https://adv-r.hadley.nz/translation.html#latex
