Second partial trendline appears on the beginning of the graph

Put the figures for the green trend line on a separate row and have the source from col C to AF. If you add =NA() to the cells that would be zeros then it won't plot those points so the trend line will appear where it should.

BSB

I did as you said, but if I set the source from C to AF then it shows me the trendline for the whole range, and when I change it to just that second part of the graph then it appears again on the beginning of the graph.

P.S. the green line is no trend line, it is the graph line from which I want to pull the trendline.

HI
you must enter the series from column C to column AF and where there is no data enter the formula =NOT AVAIL()
See the attachment at row 11.
HI,

Hi Mario, that is also one step closer but still I cannot get the trendline for the second serie, without moving the graph line to the beginning. Checkt out the attachment:

P.S. maybe I should correct myself. The trendline is there, but it goes all the way from the beginning. Hm, I think I became little bit too petty/perfectionistic
