How to start

From code

// Prepare the data. We're going to show the top ten cheese producing U.S. states in 2013 (in 1,000 pounds)
final Map<String, Float> axis = new LinkedHashMap<>(10);
axis.put("CA", 2312.895F);
axis.put("ID", 871.640F);
axis.put("NY", 751.280F);
axis.put("NM", 661.293F);
axis.put("MN", 661.293F);
axis.put("PA", 426.985F);
axis.put("IA", 267.249F);
axis.put("OH", 196.676F);
axis.put("VT", 127.346F);

// Set your data to the view
final RadarChartView chartView = (RadarChartView) findViewById(R.id.chartView);
chartView.setAxis(axis);

chartView.setAxisMax(2855.681F);         // set max value for the chart
chartView.addOrReplace("WI", 2855.681F); // add new axis
chartView.addOrReplace("OH", 281.59F);   // change the existing value
chartView.setAutoSize(true);             // auto balance the chart
chartView.setCirclesOnly(true);          // if you want circles instead of polygons
chartView.setChartStyle(FILL);           // chart drawn with this style will be filled not stroked
// ...
// and many other attributes..
