Details:

There seems to be a problem when using the axis() command to manually set the
axis size.  The problem is manifested as odd spacing of labels or odd
calculated lengths for axis tick marks.  This may have something to do with
turning off update routines while another update routine is executing.

Sample code exhibiting long x-tick lengths:


plot (1:100)
axis ([0 100 -50 250])
axis ([0 100 -50 50])


This produces the attached plot.  The commands need to be typed in
individually.  If I put them in a file and source the file then everything
works.

The following sample code causes the xlabel to be squished up against the
x-axis labeling which is incorrect.


plot (1:100)
xlabel ('x-axis')
ylabel ('y-axis')
axis ([0 80 1 100])
axis ([0 80 -50 250])


See the second attached file for the produced plot.
