public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {

    // inflate layout fragment     view rootview= inflater.inflate(r.layout.fragment_graph, container, false);     graphview graph = (graphview) rootview.findviewbyid(r.id.graph);     bargraphseries<datapoint> series = new bargraphseries<>(new datapoint[] {             new datapoint(0, 1),             new datapoint(1, 5),             new datapoint(2, 3),             new datapoint(3, 2),             new datapoint(4, 6)     });     graph.addseries(series);     return rootview; }
