This seems to have finally been fixed for FLTK (at least as of tip e066d173aae6).

semilogy (1:500)

now works as expected. Closing report.

Right. I was only looking for the tick marks (which didn't even use to show with FLTK) and completely ignored the labels. This bug is still present.

Rik,

Try ...

semilogy (1:500)

ticks are located on 3.26228, 31.6228, and 316.228

Open again?

The colorbar demos illustrate this bug.

The ticks are correct for the gnuplot backend (v4.4.0). I've verified that this behavior is present for the FLTK backend on a recent tip (11313:988d2bd6bacd).

See the attached plot and data.
The default y axis values should be in powers of 10.
Matlab R2009b just shows 10^1, 10^2, and 10^3 on the y axis.

I suspect that the x axis has the same problem, but these data
do not show that. Also, loglog likely has similar problems.

The attached plot is from semilogy(out);
The attached out.dat is the data to be read in
by load out.dat

plotting was to fltk backend.
