Log log plot

I have a set of data wich I want to plot in a log scale, not with the base 10, but with the base 2. How can I do that?

Answer 1

Try this code:

plot(log2(rand(100,1)*128))
ytick = get(gca, 'YTick')
str = cellstr( num2str(ytick(:),'2^{%d}') )
format_ticks(gca,' ',str)

format_ticks function you can download from:

See:

doc loglog

yeah, I did that, severaltimes, but I haven't found the solution there. it just doesn't say anything about changing the log base. am I missing it maybe?

[C.J. Harris]

log10/log2 is a constant, so can't you simply modify the axis labels?
