I have 2 tables in one app. One tables shows how many devices are allocated to each department (i.e. How many they should have). The other table shows how many devices they actually have in each department (some may be missing due to repairs, lost, etc.). I want to create a bar chart on the dashboard that shows the comparison of the 2 numbers. It can be a side-by-side bar chart, or a bar line chart. Is that possible?
