title: How can I create a dynamic chart that only shows the last 4 weeks?
body: <p>I want to create a chart that only shows the last 4 weeks of data. If I enter the information of a new week, I want the range of the chart to dynamically move to display the last 4 data points as shown in the picture provided. Example: When I capture Week 9, I want the chart to automatically display Weeks 6, 7, 8 and 9. See the example below.</p>
