Example scripts for two Pareto plug-ins creation:

NOTE: before applying the script create panels in Service->General->Panels .

On Central Start script:

import ParetoPlugin2
reload(ParetoPlugin2)

ParetoPlugin2.CreatePlugin(GetCustomPage("Pareto1 chart").handle, 'Pareto1')
ParetoPlugin2.CreatePlugin(GetCustomPage("Pareto2 chart").handle, 'Pareto2')

Note: plug-in does not require plug-in registration with RegisterPlugin after instance creation, because plug-in registers it self.
