Display power of 10 at axis' end

Question

My data runs from 0 to 800000 on the x-axis and I have 4 plots in a square. To make the scale readable, I\'d like to label the ticks from 0 to 8 (i.e. with %1.0t) a

Answer 1

set xtics 100000 format "%1.0t"
set label "*10^5" at graph 1, 0  offset 4

However the more conventional approach is to explain the scale in the axis label:

set xlabel "Whatever it is (x 10^5)"
