I am trying to build some charts using Oxyplot, I am using Xamarin forms on a Mac and there is no PM to run "PM> Install-Package OxyPlot.Xamarin.Forms -Version 2015.1.689-alpha -Pre" which is what I need to install the oxyplot for tamarin forms package and cannot find it on the Nuget extension for Tamarin forms.
how can I install this package???
