[[0 4 8 12 16 20] [8 5 11 16 18 14]] |ENTER|

|ALPHA| |ALPHA| LAGRANGE |ENTER|

This seems to do what i need, thanks
Is there any way to go directly to a spesific X value when this has been plotted?
I can find it in TABLE but i was hoping there was a "GOTO" function in the plot view so i could easily read values at certain points without solving the function.
