#4383 — Axis number format

Here is plot I am working with:
www.dieterbritz.dk/gnu4.pdf

It is only a partial plot and the X-axis will go further
as the program produces more data, to higher T values. I
would like all the numbers be in the form 10^*, not 1 x ..
and not converting to plain f-format, i.e.
10^{-10}, 10^{-9}, ... 10^0, 10^1, ...

How do I do that?

Hi

I don't know if there is a way to do this automatically, but for a given plot you can set the tics to be whatever you want. Here' the example:

set xtics ("low" 0, "medium" 50, "high" 100)

For your plot it would be something like

set xtics ("1^{-10}" 1e-10, "1^{-9}" 1e-9, "1^{-8}" 1e-8, "1^{-7}" 1e-7, "1^{-6}" 1e-6, "1^{-5}" 1e-5, "1^{-4}" 1e-4, "1^{-3}" 1e-3, "1^{-2}" 1e-2, "1^{-1}" 1e-1)

Note if this is too cluttered you can do just odd or even or whatever:

set xtics ("1^{-10}" 1e-10, "1^{-8}" 1e-8, "1^{-6}" 1e-6, "1^{-4}" 1e-4, "1^{-2}" 1e-2, "1" 1)

Just make sure when you set your terminal you set "advanced", as I don't think superscripts work otherwise (might be wrong though).

Best


Gavin

Enhanced mode is the default since ~5.0

And there is a host of advanced format specifiers available for the 
use with gprintf() and in gp format definition strings.

    set xtics format "10^{%T}"

check "help format specifiers"

Cheers, Karl
