Y2 and Y2[-1] Showing same value

[PKeyes505]

I am trying to follow along with the blog post below. Why is P1 (Y2) and P2 (Y2[-1]) the same value, yet in P3 (Y2-Y2[-1]) I get the expected difference?

There was a typo in the code computing the plotter data table. Fixed in source. Thanks for reporting!

Your P8 formula contains a typo (an extra closing bracket). Instead of

(Y2-Y2[-1])/(t-t[-1]))*60*k+o

it should be

(Y2-Y2[-1])/(t-t[-1])*60*k+o

New builds are produced right now and should be available in about half an hour here:
