A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Hi,
Select the entire dataset (including the header row) and go to Insert > Table. Click on any one cell in the Table and go to Data > From Table/Range. In the Query Editor, select the first 3 columns, right click and select "Unpivot other columns". Rename columns, if required. Click on Close and Load.
Now try to build your desired chart.
Hope this helps.
