How to scale the axis in Gnuplot
I have the x and y axes with large numbers (1000, 2000, etc.) But I wish to re-write or re-scale these without changing or rescaling the data, such that 1000 is 1 in the axis, etc. I'm not looking for 1x10^3. Just letting 1000 be 1. Is there any way I could do that?
The easiest thing to do is rescale the data on input:
plot 'datafile' using ($1/1000.):2 #assume x-data is in first column
Now as far as gnuplot is concerned, you gave it 1., not 1000.
