Set number format in plot tick labels?

[Matthias Brennwald]

Dear all

Is there a way to set the number format used in the tick labels of a
plot? I want to print all numbers in exponential notation. For instance:

--------------
x = logspace(3, 7, 5);
semilogx(x,sqrt(x))
--------------

With Octave 2.9.15 and gnuplot this produces a plot with the following
labels on the x axis:

        1000 10000 100000 1e+06 1e+07

I'd like the labels to look as follows:

        1E3 1E4 1E5 1E6 1E7

Is there a way to achieve this?
