hello, could you please show me how to set up my work sheet in the way that I can plot my data as; Day versus voltage (mV). My current chart has Date on x-axis, I tried to find a way to change that by created column F using datedif excel formula: DATEDIF($B$2,B116,"d")+1; this didn't work so well; and then i modified it to DATEDIF($B$2,$B$116,"d")+1 that didn't work either since as you see it gives me 1.00 for all. Is there any other way to do this? Please help. thank you
