I write a C#-application at the moment. For my finance data, I want to use a bar chart. After I searched a lot on Google, the best way seems to be Google Chart API.
My problem is, that it should not be necessary that I have internet-access when I start my application.
Is it possible to work with Google Chart API without internet-access? Or what is a good alternative for a bar chart in WPF?
Google APIs work online only and you cannot consume them while offline.
about alternatives, the MS Chart control should be free, see how to use it from WPF or SL here:

for commercial level and feature rich controls, personally I love the XtraCharts from DevXpress, there are also others from Telerik and Software FX but XtraChart is really easy to use and powerful.
