How do I update a graph weekly in excel without overwriting past week information

Hello anyone who can help. I am new on this forum, and I have been searching different forums for hours trying to find out how to do what im trying to do, and hopefully someone here can help.

I have a excel workbook with multiple sheets, with about a thousand rows of data. All the data is being exported weekly to another sheet in the workbook with a graph that will update the information. right now I am manually entering the information into the graph sheet weekly, which takes a long time. I was told that excel can do this automatically.

so here are my questions.
I have created a small example In the image I have attached, the information in orange is the info that I am going to be changing from day to day. Every Friday I want the area in yellow to automatically take the information in orange and import it into a new column and add the appropriate date as the header, which will then add itself to the graph, so i don't have to enter it manually.

Is there a way to make this automated so it updates the chart with the new numbers but keeps the old ones?
Is there a way to do this without some super advanced VB script, as I have no idea on how to use VB scripts?
Is there a way to make a "button" of sorts that automatically updates the information when pressed?

Hopefully I have explained what I am trying to do well enough. I could use any help that anyone could provide as manually entering this info every week takes hours.
Thanks for any help!
