specifying axis length

[hellbunnie]

Hi there,

I was wondering if there's a way to specify the length of the x or y
axes in a graph, by default the graph axes resize to the length of the
highest point on that axis, but I'd like to display, for example, a
barchart of percentage values on an axis that goes up to 100, even
though none of the data points is 100%.

Thanks,
Kathryn.
