Charting Non-Contiguous Data Ranges

yea.. very much what i was looking for, (although reversed) but in order to get that chart, i guess I will need to re-organize how the data is entered.. one reading per row instead of 5. Sort of how you did.

This is something I am considering. However it leads to another problem I would have to figgure out.

If i use date in column A, time in column B, and reading in column C, I need to feed the frequency data (and even that chart) a dynamic range that would include only readings who's dates are current date minus 7 days, or current date minus 30 days.
