How to Create a Dynamic Chart in Excel

In many situations you collect data every day (sales figures, stock prices etc.) for weeks, months and years, while all you want to show in the chart is the last week or two. I’ve seen many people spending a lot of time updating the chart manually every day, so here I will show you how you can make a dynamic chart that always shows the last 7 days. Of course, you can use the same technique for any number of days, weeks or months.
