What if you have multiple custom fields and you want to have all of them in one chart? Let’s assume you want to compare the values of three different number fields over time. You can do that by adding them one by one.

In this example we’ll use the multibar chart. Pick one of the custom fields as the unit for the chart. After that, use the Add custom field button to add the other two fields.

Here’s the final chart with three different metrics, grouped by week:

The unit shown on the left axis will be the field that was selected first. You can rename the unit to whatever you like it to be in the Chart format section. If your custom fields are in different unit, you can use the dual axis line chart instead.
