R visual - responsive visualization in power BI

I had created some visualizations using R visual and pin it on my Power BI dashboard.

The font size was responsive to the tile size that i set.

However, since yesterday (28.06.2018), the font became exstremly small until unreadable after report refresh.

No matter how i adjust my font size in R script, and how big the font looks in Power BI desktop, it still show tiny font in my power BI dashboard.

 

May i know how to solve this issue? How to make the visualization responsive to the tile size in power bi?

Thanks.

Hi, thanks for your help reporting this bug.

There was a bug fix a little while ago that appears to have unintentionally led to this regression. We already know the fix, it is currently in the pipe to be deployed to general production next week, around 7/13.

In the meantime if this is causing issues, there is a workaround. You can add the following lines to the beginning of your R script:

if (exists("powerbi_rFontName")){

  library("showtext")

  showtext.opts(dpi = powerbi_rPngDeviceDpi)

  showtext.auto()

}

This should make the text appear normal size in service without affecting desktop behavior, and should not cause any issues in service once the fix is deployed.

Same here - and pretty sure it wasn't an issue a month ago when I last looked. Now my R visual looks fine on desktop, but once uploaded to the Service the font looks very small, despite whatever changes I make to the font within the plot / theme etc

Are there certain R packages that are not available on the Power BI Service perhaps? Surely not the problem here as I'm only using dplyr, ggplot2 and tidyr. Screenshots below - Desktop first, then same visual once published. Code below that.

DesktopDesktop

ggplot() + 
  geom_bar(data=ot1, aes(x = att, y=count,fill=score),  stat="identity", position = "stack") + 
  geom_bar(data=ot2, aes(x = att, y=count,fill=score),  stat="identity", position = "stack") + 
  geom_text(data =labeldata, aes(x=att,y=y, label = count), size=6, colour = "black") +
  coord_flip() + 
  scale_x_discrete(limits= rev(levels(ot1$att)))+
  theme_minimal() + 
  scale_fill_manual(values = c("#d7191c","#fdae61","#ffffbf","#abdda4","#2b83ba"))+
  xlab("Attribute")+
  ylab("Count of Beneficiaries") +
  ggtitle(paste("Initial Stars By Attribute (n=",totalDS, ")", sep='')) +
  theme(axis.text.x=element_blank()) +
  theme(plot.title=element_text(size=2

 

Help!

Thanks
Pete.

Similar to your script, I have used the coord_flip() function. My visual works perfect when my plot is vertical. When I use the coord_flip() to rotate my visual, the plot rotates but the rendering looks weird. Any idea?

My problem was just the label font being too small once published, which the suggested fix sorted out. Hard to say based on "rendering looks weird" but sounds like you have some other problem not related to the one raised here.

Sorry, managed to lose a photo in previous post - here's what the visual looks like once published...

Gaah! And I chopped off the end of the last line of code (maybe I enjoyed England's penalty shoot out a bit too much last night?)

Last line reads like this...

theme(plot.title=element_text(size=20))

I had similiar issue with the R visual lable after published to the server, it is shown corrected in the desk top, but after I published to the server, the lable text shown each single word as 90 degree, but the whole lable to the angel been set (screen shot as 45 degree). Not sure if there is any changes in the server site. Can some one please help to check.

Exactly what i am facing now. Hope someone can answer.
