Hello,
This is how I see the chart using the info you gave me (except for the data content, I created different set of values).
Exporting the list and the web part would help me a lot.
To export the list, go to list settings, then pick save list as template, include the content then save it to a local folder then attach it to the tread.
For the web part go to the web part verb (put the page in Edit mode, select the web part , go to the top right corner and from the menu select Export).
A web search would help too.
