how to specify plot range in LAS?

[Zhangfan Xing <xing@xxxxxxxxxxxxxxxxxxxx>]

I have not figured out how to specify plot range in LAS.
This is needed when data has a few bad values
(either too large or too small). Without the ability
for user to specify wanted plot range, the output
plot is skewed (by bad values) and featureless.
I have tried "Contour levels" and "Fill levels" under
"Options" button, but neither seems to allow me do so.

Thanks,
