3-系统方案A(Activity界面跳转,携带数据，显示曲线界面)

        mAchartengineMethod.setXYMultipleSeriesRenderer(Color.RED, Color.BLACK, Color.RED, Color.BLACK,

        mAchartengineMethod.setXYSeriesRenderer(Color.RED, 10.0f);//设置一条线加入渲染器
        mAchartengineMethod.setXYMultipleSeriesDataset("温度(℃)");//设置这条曲线的数据集

        mAchartengineMethod.setXYSeriesRenderer(Color.BLUE, 10.0f);//设置一条线加入渲染器
