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?

Hi Purna..
Again a great tip.. Its a great way to convert Fractional Time..
By the way.. Excel has two great and rarely used formula..
=DOLLARFR(7.8,60) and =DOLLARDE(7.48,60)
basically US Account person uses those to convert some currency denomination.. and we can use it to convert Year(i.e 3.11 Year = 3 year 11 month) and Week(6.5 week = 6 week 5 days), in the same manner...
This doesn't work for me. When applying the custom format of [h]:mm to 7.8 I get 187:12
Any ideas why?
@Jason
7.8 in Excel talk means 7.8 days
=7.8*24
=187.2 Hrs
=187 Hrs 12 Mins
If you follow Chandoo's instructions you will see that he divides the 7.8 by 24 to get it to a fraction of a day
Simple, assuming the fractional time is in cell A1,
Use below steps to convert it to hours & minutes:
1. In the target cell, write =A1/24
2. Select the target cell and press CTRL+1 to format it (you can also right click and select format cells)
3. Select Custom from “Number” tab and enter the code [h]:mm
4. Done!
Hi, sorry to point this out but Column C Header is misspelt 'Hours Palyed'
good one
So how do I go the other way and get hours and minutes to fractional time?
If you have 7.5 in cell A1,
- Use int(A1) to get the hours.
- Use mod(A1,1)*60 to get minutes.
If you have 7:30 (formatted as time) in A1
- Use hours(a1) to get hours
- Use minutes(a1) to get minutes.
I had the same issue. You can solve it by changing the format as described above:
Right click cell > Format Cells > (In Number tab) > Custom > Then enter the code [h]:mm
([hh]:mm and [hhh]:mm are nice too if you want to show leading zeros)
Thanks guys, these are the tips I'm looking for.
...dividing the number of minutes elapsed by the percent change is my task - "int" is the key this time
It doesnt work for greater than 24 hours
It returns 1:30 for 25.5 hours. It should have returned 25:30
Ideally I would right function as
=QUOTIENT(A1,1)&":"&MOD(A1,1)*60
Sorry, replied to wrong comment....

Clever use of MOD here to extract the decimal part of a number. Divide a number containing a decimal by 1 and return the remainder. Humm. Very clever.
Thanks very much, extremely useful !
