<div>However you should be able to create a stereographic projection that does not include the poles and have grid lines as well as labels if you are willing to have rectangular boundaries. </div><div>You will need to play with the resources: mpGridAndLimbOn, mpGridSpacingF (or alternatively mpGridLatSpacingF and mpGridLonSpacingF).
