Looking at the OxyPlot.Core NuGet package it contains a Portable Class Library (PCL) assembly that targets net4+sl4+wp71+win8 so you should be able to install it into a MonoAndroid project.
Means that the bindings aren't complete by the looks of it. Have you tried OxyPlot - docs are awful but it's a hideously powerful and very flexible plotting system
I posted the query just to check if there are any better suggestion to use simple chart controls other than what I found. If there is none, I've made some progress, I've got working https://oxyplot.co
