```This graphs f from 0 to 8 Pi on a logarithmic horizontal scale:

f[x_] := 1 + Abs[Sin[x]/x]
Plot[f@Exp@x, {x, 0, Log[8Pi]}, PlotRange -> All];

If you want both scales to be logarithmic, use

Plot[Log@f@Exp@x, {x, 0, Log[8Pi]}, PlotRange -> All];

The first is always possible if you only have positive x to deal with,
and the second is possible if x and y are BOTH positive.

How can I plot (2d) functions using a logarithmic scale for the X-axis?

Thanks
