Data Studio from Google is an awesome data visualization tool. With its ever growing list of features there may be a few that have flown under your radar. One of those features is creating your own formulas which is what I am going to expand on.
Data Studio makes creating visually appealing and interactive reports a cinch, it can also cause a headache if anyone edits the report or makes changes and accidentally breaks the report or data source. This has been a hurdle to get over when issues arise, until now.
Google Data Studio allows you to beautifully visualize your data in charts, but only from a single source, until now. Google has released a Data Blending Beta for Data Studio which allows you to create blended charts within your dashboards from multiple data sources. This is very helpful when you want to gain additional insights from your data and need to combine multiple sources to analyze and visualize data side-by-side. This will save time from having to manipulate your data from another source in-order to input it into Data Studio.
