[Gnuplot-info] ignore invalid data from an input dataset

[Jon <dev...@gm...>]

Dear members,

I am trying to skip data which is beyond the valid range. The usual way like


p 'aa' u 1:(($2>5)?$2:1/0) w l

leaves in the figure broken lines, which does not look very good.

I am wondering whether I can do the following two ways

(1) remove these points on the x axis?
(2) reset the value of these points as average of the nearby two points(one
before it and one after it)?

Thanks,

Sincerely,
Jon
