Hi friends,

I have a chart with 20 rows and columns. I need to compare 2 rows at a time
in a simple line chart to see thier progress, for example row 1 with row 5 ,
then 4 with 10 and then 1 with 16 etc.

what would be the easiest way to achive this, for now I have to do it by
selecting the rows each time by edit data.

Can I have 2 dropdown menus above the chart with the column names so that
the chart would display the values I chose.

Thanks for your help.
