Is there any quick way to select which series, or sets of series I want a chart to show?

I have made a dynamic chart (with great help from broro183) that charts 4 series of data. I may want to show 1 series, or a combination of 2,3, or 4. I put in a control box, but that is really throwing off the data, for a reason I cannot figure out.

FYI, because of the way I receive the data, I have date headings across the top row, the 4 series of data in 4 rows below that. I know, I know...it would be more elegant to have it in columns, but I really don't want to go through the hassle of transposing into columns.

Thanks in advance.
