Excel plotting data incorrectly

[gc4789]

Can anyone help me figure out why the data in an excel table is not plotting correctly on a line graph based on the values I have used? I cannot seem to get to the bottom of it! 

I also can't see anywhere for me to attach the file as it says file type not supported when I drag and drop on my Mac.

If you cannot attach a file, you can upload it to a cloud store such as Microsoft OneDrive, Google Drive, Dropbox or Box. Each of those lets you obtain a link to the uploaded file. You can paste the link into a reply here.

Thanks. You selected the wrong chart type. It is now a Stacked Line Chart. It should be an ordinary Line Chart.
