It’s great that you can adjust the formatting on charts to basic templates, or even for specific series / values in the chart builder, but what we’re looking to do is get a quick visual representation of whether our metrics are on or off track.
To do this, we want to have graph colours change based on the actual value of the metric and whether it is in or out of a particular range. The closest comparison I can give would be Conditional Formatting in Excel/Sheets.
For example, if the report is showing number of active customers, we want it to be green if 5 for example, and red if 1. Even better if it’s based on criteria/a range, such as 5+ = green, 3-4 = yellow, 1-2 = red.
