#483 xlabel loses its bottom part

[Chuong Nguyen]

This happens with Freemat 4.0 and svn versions on Ubuntu 9.10, 64bit, Qt 4.5.2. Code example:

plot(1:10, (1:10).^2)
xlabel('x axis')
ylabel('y axis')

The figure will show a graph where the bottom part of the label 'x axis' is hidden below the figure area. This also happen to images exported from the figure.
