In the attached chart with 2 plots. Row plotted is dependent on the value in V1 of Sheet5, which is dependent on the selection on that sheet.

The chart has 2 sets of axes. Only one vertical one showing, since they're both always 0 to 80.
This is intriguing; what are you looking to do, what are you looking for?
Re:"will allow me to see any points of changes to the data if any occured", I strongly suspect you can find these changes with some relatively simple arithmetic.
