Avoiding a specific data point from chart 2

[quark]

Greetings,

This is about a biological test that needs extrapolation by graphical means, with time on x axis and biological data on y axis. When y vaule is less than a certain value, say 1.6, I want excel to omit this point and draw the graph upto the penultimate point. Even when I am using a condition like if(B4<=1.6,"",c4), excel treats this point as zero in the graph. Any solutions for this?

Regards,

Use filters.

Filter the Y data for "Less than 1.6".

How about: (B4<=1.6,NA(),c4),

=====================================
(2B)+(2B)' ?

Sorry, forgot the if.
if(B4<=1.6,NA(),c4)

The NA() function is ignored by plots without inserting a zero.



=====================================
(2B)+(2B)' ?

Pete,

Great! That works perfectly.
