Petr,

I verified that "unset multiplot" was in place. The problem has to do  
with a missing semicolon.

The line below produced the gnuplot error.

plot "-" binary array=2x2 scan=yx origin=(1,1) dx=1 dy=1 using 1 title  
"" with image plot "-" binary array=4x4 scan=yx origin=(1,1) dx=1 dy=1  
using 1 title "" with image ;

If I understand correctly, it should be ...

plot "-" binary array=2x2 scan=yx origin=(1,1) dx=1 dy=1 using 1 title  
"" with image; plot "-" binary array=4x4 scan=yx origin=(1,1) dx=1  
dy=1 using 1 title "" with image ;

Please verify this works for you. I'm unfamiliar with this part of the  
code, so any comments are welcome.

Ben
