Excel Graphing Line References off when chart is a sheet.
 

I have noticed that when any graph is created in EXCEL and you hover you
mouse over the dataline you receive that corect response. If you convert the
chart to a sheet, the hover of the data line is now not representative of the
the y axis directly below it. The data being graphed is correct now the hover
represents the "series" (x-Axis) correctly but does not represent the "Point"
(y-axis) correctly at all. Tne Y-axis datapoint reference is wrong. Any help?
