Yesterday we saw a beautiful example of panel charts with R. Today let me show you how to create the same (or even better) with Power BI & R.
What you need:
- Power BI Desktop and R
- Raw data set – rem-data.csv
Creating Panel Charts in Power BI with R
- Load CSV data in to Power BI
- Edit the query in so we can transform the data in to Pivot shape in Power Query
- Apply below steps in Power Query
- Group data by Group and Branch with aggregations on count (named Branch Count) and All rows (named Ratings)
- We get a totals by group and branch level.
- Expand Ratings table and show only Ratings column
- This creates a table with all group, branch and rating combinations along with branch total
- Group again, this time on Group, Branch, Branch total and Ratings with aggregation on count.
- Calculate count as percent of Branch count
- Format the percentage as percent
- Close and apply to Load this data in to Power BI
- Group data by Group and Branch with aggregations on count (named Branch Count) and All rows (named Ratings)
- Insert R script visualization
- Add Group, Branch, Ratings and Pct to values area. This creates a dataframe with all 4 columns.
- Add below R script and your visualization is ready.
library(tidyverse)
ggplot(data=dataset) +
geom_bar(aes(x=Rating, y=Pct), stat="identity")+
scale_x_discrete(limits = c("NME","AME","SP","OP","NR"))+
facet_wrap(~Branch, nrow=1)+
theme(strip.text.x = element_text(size = 8))
To run the R script, simply press play button in R script editor pane.
Enhancing your visualization – Adding a slicer on Group
This creates a truly powerful interactive panel chart in Power BI. Simply add Group as a slicer and play with it. Every time you select a new Group, Power BI runs the R script with filtered data fed to the dataframe. There is a second or two lag, but the wait is totally worth it. 🙂

Here is a video outlining the entire process along with some tips on how to use R in Power BI. Check it out below or on Chandoo.org YouTube channel.

Have you tried Power BI yet?
I am playing with Power BI for last year or so and I am in love. You are going to hear more about it on Chandoo.org for sure.
What about you? Have you played with Power BI yet? What are your thoughts?

You are right, Chandoo. I was playing with the colour numbers last week and some of them don't appear different from each other. Others are totally different from yours.
@Duncan
Each version of Excel, post 2003, renders colors slightly differently
Different language versions may also have different default color palettes
Hello in french
excel 2010
colo1 = couleur1 = black
[couleur1]; [couleur2]; etc..
@Hui, thank you very much again for this great post.
However - under Excel 2007, Hungarian version your solution does not work with color names. I've tried both English and Hungarian names, but drops an error message "not valid formats"
Do you have any idea how to solve this issue?
thanks in advance
@Andras
Without a Hungarian version of Excel 2003 I don't think I can assist
Have you tried using the colour numbers? I couldn't get the names to work (despite using an english version of excel). but it did work with the numbers though. I left out the "u" and was easily able to produce burgundy using [color9]
Here a possible solution: find an English version of Excel, write there the formats using English names, then open the file in the Hungarian version and see the translation.
In Excel 2007 I can't get the colour names to work e.g Sea Green but the numbers do e.g color3 - colour3 does not work so I must bow to the country that has stolen my language (ha ha!)
Hey chandoo, nice Tip!
Wouldn't be easier just apply some conditional formatting for negative numbers and another for positive numbers? Or there's some cases that you can't do that?
Unfortunately the TEXT function doesn't color the cell as number formatting does.
Hi Hui,
Great post Sir, love the new way of formatting with color numbers.
I am using 2007, and it leads me to the last color number 56.
Thanks Hui.

Thanks Hui - works a treat!
Thank you, very helpful.
Trying to figure out if it is possible to apply color only to a part of the cell?
E.g. I have a value formatted as Accounting with a currency symbol.
Those I find somewhat distracting though necessary. If I could make them less obtrusive by coloring them gray while the number would stay black, that would be great. Tried tinkering with the format string, but didn't get the desired result. Single color for complete cell value works, but coloring just part of it could not be achieved. Maybe somebody managed that?
Exactly what I was looking for - thank you!
colour in the Australian doesn't work - we have to go American and no problem.
I always thought is was 56 colours notice you have 57. Cool.
thanks
