This article will give you the steps on how to tailor your charts so they are only display for certain periods of time.
First you'll want to head to the "Options" tab of the Chart Builder. If you are looking to edit an existing chart, you'll want to find that chart on your dashboard, hover over it and then click "Edit".
You'll want to look towards the bottom in the "Custom Period" area. Here you will be able to specify when you want a chart to start and/or end. If you leave the "Start" period blank we will automatically go back and visualize data that is filled in. If you leave the "To" period blank then we will visualize up to the most recent time period for that data.
Click "Save" and you will be on your way!
