# You can manually set the subaxes and exceed the axes ranges.
# The width of the regular axes can be modified by a size paramater.
# While most axes do not have a size parameter, it can be added to
# any existing axis very easily. For linear axes so called sizedlinear
# and autosizedlinear axes are defined by PyX already.
#
# Note: The mytuple/lambda construct is currently a work-around to
# create tuples within the mathtree expression evaluator.
