I want to use excel offset function to build a dynamic chart. Basically, I want my line chart always show the data for last 5 days. I know how to do it for a single variable, but for multiple variables, I have no idea. Can you help me?
My data is in below format. enter image description here
In the chart, there should be four dynamic lines--area1 vol, are2 vol, area3 vol, and the total vol.
Thank you.
