I'm making heatmaps using geom_tile for correlation matrices.
Using my previous MRE:
require(ggplot2)
require(plotly)
randomName <- function(n) {
random.string <- rep(NA, n)
randomizeString <- function(x) {
a <-sample(letters, 1, replace = TRUE)
return(a)
}
return(paste(c(sapply(random.string, randomizeString, simplify = TRUE)), collapse = ""))
}
xvar = replicate(10, randomName(15))
df1 <- data.frame(x = xvar, y = xvar, z = runif(10) )
g = ggplot(df1, aes(x,y,fill=z)) +
geom_tile() +
theme(axis.text.x = element_text(angle = 45, vjust = 1, size = 12, hjust = 1))
ggplotly(g)When you hover over the volcano examples here:
https://plot.ly/ggplot2/geom_tile/
all of the numbers are lit up in the tooltip. Sometimes these matrices can be large and having it tell you which x and y you're on as well as the value would be really needed.
This exclusion appears to have been made on purpose:
https://github.com/ropensci/plotly/blob/master/R/ggplotly.R#L195-L203
Though, I'm not sure I understand the code completely.
When I try and force a tooltip using tooltip = c("y", "x", "fill") it doesn't work. I would really like the ability to force tooltips, because I don't think it's misleading in my case.
