Multiple Shading within a Scatter Chart

I'm working on a criteria matrix in Excel 2010 that automatically plots a single member in a Scatter Chart based on the two values. There are 4 suppliers listed in Column D starting in cell D4 thru D7. The "x" value is listed in Column E starting in cell E4 thru E7. The "y" value is listed in Column F starting in cell F4 thru F7.

The scatter chart will plot the points correctly, however, there are two issues:
1) If I try to insert a data label using the "Series Name," or in this case, the supplier's name, it will lists ALL of the suppliers Column D. It will not list the single supplier listed in cell D4.
2) The scatter chart appears with gridlines as a 4x4 matrix with a total of 16 cells. The "x" and "y" axis both start at 0 and go to 4. I can shade the entire chart one color. However, I want to shade some of the cells with darker and lighter shades.

Any thoughts on the two items listed above?
