Details:

When using fltk I only get a subset of my data plotted with the "plotyy"
command (no matter which XY series) (see attached figA_fltk.png).
Using gnuplot I get the picture that I expect (see attached figB_gnuplot.png)

For some reason fltk consistently skips a number of data points before
plotting the next in a series.
Adding series makes no difference; these are plotted at the same X locations.

FYI: error was hit on Octave-3.4.2 under MinGW but occurs identically on
MandrivaLinux 2010.2 (with Octave-3.4.2).
I got more or less the same (erroneous) result in 3.2.4 (MinGW), save for some
backward incompatibility issues with the attached script when adding a third
series. So this issue exists for some time now.

Reproducable using the attached plotyy_fltk.m & plotyy_fltk.mat files:
put them together in a some directory;
in Octave, run plotyy_fltk.m
