*Disclaimer: For this video I have used data from the Google Merchandise Store Google Analytics which is publicly available.
A combination chart visualizes data for several metrics to help you compare. In this video I show you how to create a combo chart in Google Data Studio. I am creating a trend chart for sessions, unique purchases, product adds to cart and revenue for a period of 13 months. In this video I also show how to style a chart and choose different colors for each metric.
If you are just starting with Google Data Studio, I have written a detailed Google Data Studio Guide to get you started.
