Hello, I have weekly data (more than 1000 data points each week) collected that I would like to plot them using excel. I want to know how to add each week data into the same worksheet without having to re-plot the data again and again. I also would like to have the axis label by monthly (for example: Day 1, Day 30, Day 60, etc.) Thank you so much for your help. I'm truly appreciate it.
Sincerely,
Wish I know Excel more.
