Conditional TREND function for values greater than 0

[bieniman]

Hi all,

=TREND(known_y's,known_x's,new_x's,const)

I am trying to use the TREND function to return a value for a certain x (in this case 10).
The known y's come from column A and known_x's from column B.
However, I only want to get the trend for functions for values greater than 0 in row C.

I tried {=TREND(IF(C1:C4>0,A1:A4),IF(C1:C4>0,B1:B4),10)} and this returned #VALUE!. It should return 60 right?

Does anybody know how to do this?

below is an simple table to illustrate:

[TABLE="width: 500"]
<tbody>[TR]
[TD][/TD]
[TD]A[/TD]
[TD]B[/TD]
[TD]C[/TD]
[/TR]
[TR]
[TD]1[/TD]
[TD]12[/TD]
[TD]2[/TD]
[TD]1[/TD]

[TR]
[TD]2[/TD]
[TD]24[/TD]
[TD]4[/TD]
[TD]1[/TD]

[TR]
[TD]3[/TD]
[TD]44[/TD]
[TD]23[/TD]
[TD]0[/TD]

[TD]4[/TD]
[TD]48[/TD]
[TD]8[/TD]
[TD]3[/TD]
[/TR]
[TR]
[TD][/TD]
[TD][/TD]

</tbody>[/TABLE]

Hi Bien

I would delete the rows with 0, instead of just masking them, so that Trend() only gets number values.

In F2, array entered:

=TREND(N(OFFSET(A1,SMALL(IF(C1:C4>0,ROW(C1:C4)-ROW(C1)),ROW(INDIRECT("1:"&COUNTIF(C1:C4,">0")))),0)),N(OFFSET(B1,SMALL(IF(C1:C4>0,ROW(C1:C4)-ROW(C1)),ROW(INDIRECT("1:"&COUNTIF(C1:C4,">0")))),0)),10)
