I'm trying to generate some schematic figures using gnuplot. My x scale is of angstrom and the y scale if of mV. Currently, I have the x scale goes like:
0 1e-9 2e-9 3e-9 etc.
And my y scale goes like
-0.07 -0.06 -0.05 etc.
And I want them to be
0 10 20 30 etc.
-70.0 -60.0 -50.0 etc.
respectively. Is there a way to do this from within the gnuplot (apart from setting the xrange an yrange parameters and multiplying the values by the appropriate amounts)?
There are two ways that I can think of:
You could make use of set xtics
(see documentation here)
Then you can explicitly specify what value on your axis will receive which label. So something like this:
set xtics ("0" 0, "10" 1e-9, "20" 2e-9, ...)
should work. Proceed accordingly with the y axis (set ytics
)
You could multiply your values accordingly. (Like what you have mentioned in your question)
plot "Data.dat" u ($1*1e9):($2*1e2)
