R font size too small on PowerBI Service.

[Anonymous]

When I publish a report with a R chart on PB service the fonts became too small. Both in R Studio and PB Desktop seems OK.

The problem ins't with the script since i've tested with plot(dataset) only, also changing the font size on script doesn't affect PB Service.

I agree with rviana.  Existing pre-published reports on the service are also affected (axis text significantly shrunk and are unreadable).

I am seeing the same behavior across two service tenants. Even previously published reports that haven't been touched in months, which displayed R script visuals with normal font size in the past, now have small, unreadable fonts. In many cases, Power BI Service pulls up the (presumably cached) normal-looking visual first and then repopulates the visual with one that has the tiny text size.

Hi all, 

I have reported the same issue internally: CRI 75525272. Will update here once I get any information.

I'm having the same issue.

For an easy way to reproduce this issue, you can use the following simple R code (and any dummy values in the "Values" data field as the mpg data frame comes with R):

library(ggplot2)

p <- ggplot(mpg, aes(class))
p <- p + geom_bar(fill="blue")
p <- p + theme_classic()
p <- p + theme(
axis.text.x = element_text(size = 14, angle=45, hjust = 1),
axis.text.y = element_text(size = 14),
)
print(p)

Viewing locally all custom R visuals and R visuals packaged as pbiviz files  are fine, but when viewing online I have the same issue as above no matter what the text size in the code above is set to.

I am having the same issues as well. All text and x / y axis information is substantially shrunk in my online power bi reports. Everything looks normal when using power bi desktop.

I'm having the exact same problem - all my custom R visuals that used to appear fine now have a tiny text size on the labels, or they dont appear at all, and the y axis title disappears completely

Hi,
I'm experiencing the same problem.

I paste below an example code: the color customization works well, while the text customization clearly has problems.

library(grid)
library(gridExtra)

d <- head(iris, 3)
g <- tableGrob(d)

find_cell <- function(table, row, col, name="core-fg"){
l <- table$layout
which(l$t==row & l$l==col & l$name==name)
}
for(i in 2:4){
for(j in 2:6){
index_fg <- find_cell(g, i, j, "core-fg")
g$grobs[index_fg][[1]][["gp"]] <- gpar(cex = 4, col = "green")
}
}

grid.newpage()
grid.draw(g)
