Hi,
I have the following data:

X Red Green Blue Intensity
0 64 69 72 67.847

And so on for 300 rows. I Have 80 sets of this data (before and after) to graph. My goal is to have the graphs side by side and have a pull down to indicate the sample (1-40) and update the before and after graph. I have done this before using pivot tables when I needed to graph averages, but not when math isn't needed on the data.

Thanks in advance for your ideas

Tim
