Re: GNUPLOT: Scaling of x-axis

Moin,

Oliver Mertens schrub:

Could someone please tell me how to scale the
x-axis under gnuplot?

plot 'data' using ($0 / 10.):1


Thanks for your answer!

Now, let's assume there are two columns given as
x1 y1
x2 y2
x3 y3
. .
. .
. .


Same way: plot 'data' using ($1 / 10.):2

1. How do we scale the x-axis and leave the y-axis unchanged?
2. Same question in the other way around:
How do we scale the y-axis and leave the x-axis unchanged?

plot 'data' using 1:($2/10)

$n means the n'th column, you could calculate with the value in
that column as you like. Even

plot "data" u (sin($1+$2)):2

is allowed
(which will plot y1 over sin(x1+y1), y2 oder sin(x2+y2),... if
you ever need that:-))

In other words:

plot "data" u 1:2

is the same as

plot "data" u ($1):($2)

and in the braces you could make every calculation you want.
$0 ist a special column which is interpreted as if it contains
the line number.
