您可以覆盖LineGraphView drawSeries并更改绘制对象。

类似的东西：

GraphView graphView = new LineGraphView(this.getActivity(), "GraphView") {
   @Override
   public void drawSeries(Canvas canvas, GraphViewDataInterface[] values, float graphwidth, float graphheight, float border, double minX, double minY, double diffX, double diffY, float horstart, GraphViewSeriesStyle style) {
      paint.setStyle(Style.STROKE);
      paint.setPathEffect(new DashPathEffect(new float[] {10,20}, 0));
      super.drawSeries(...);
   }
};
