Can we change vertical height from millibar to Km. in ferret

["Yogesh K. Tiwari" <Yogesh.Tiwari@xxxxxxxxxxxxxxx>]

Dear Ferret users,

Using  ferret commands can we change the (Y-axis) unit from millibar in 
to the kilometer of any "plot" generated by the ferret.

Thanks in advance for any help,

Regards,
Yogesh
