A picture would help immensely in this situation. However, if I understand you correctly, the user should be able to hover over a point or header on the graph, then click the horizontal bars in the bottom right corner of the tooltip. This will show them the value that is displayed. Let me know if this helps.
Thanks for the response, but I believe I should have mentioned an additional element. The user knows how to View Data, but wants to be able to select the data and then simply copy and paste (instead of having to export).
