Java代码中，通过以下方法添加一条属性： 30 | 31 | radar_chart_view.insertType("法术", 800, 1000); 32 | radar_chart_view.insertType("攻击", 700, 1000); 33 | radar_chart_view.insertType("物抗", 550, 1000); 34 | radar_chart_view.insertType("魔抗", 500, 1000); 35 | radar_chart_view.insertType("移速", 800, 1000); 36 | radar_chart_view.insertType("天赋", 400, 1000); 37 | radar_chart_view.insertType("暴击", 80, 100); 38 | radar_chart_view.insertType("金钱", 9000, 10000); 39 | 40 | 3. 添加过后必须设置RadarChartView.Config，该对象用来配置雷达图表的属性: 41 | 42 | RadarChartView.Config config = new RadarChartView.Config() 43 | .setMaxLevel(5) 44 | .setCenterPointRadius(5) 45 | .setChartWidget(0.8f) 46 | .setFillColor(0xff268415) 47 | .setSecondFillColor(0xffcd2626) 48 | .setValueLineSize(1) 49 | .setValuePointRadius(5) 50 | .setBackgroundColor(0x88985615) 51 | .setTextColor(0x88985615) 52 | .setTextSize(40) 53 | .setCanScroll(true) 54 | .setCanFling(true) 55 | .setValueBackgroundAlpha(0.2f) 56 | .setTextPosition(1.1f) 57 | .setPointRadius(2); 58 | radar_chart_view.setConfig(config); 59 | 60 | 4. 效果图如下： 61 | 62 | ![image](https://github.com/luweibin3118/RadarChartView/blob/master/app/Screenshot_20171226-185310.png) 63 | 64 | 5. 如果要实现多个对象的属性对比，需要通过compareType方法添加对比属性： 65 | 66 | radar_chart_view.compareType("法术", 700, 820, 1000); 67 | radar_chart_view.compareType("攻击", 900, 750, 1000); 68 | radar_chart_view.compareType("物抗", 550, 600, 1000); 69 | radar_chart_view.compareType("魔抗", 750, 800, 1000); 70 | radar_chart_view.compareType("移速", 800, 750, 1000); 71 | radar_chart_view.compareType("天赋", 800, 900, 1000); 72 | radar_chart_view.compareType("暴击", 80, 70, 100); 73 | radar_chart_view.compareType("金钱", 9000, 9500, 10000); 74 | 75 | 6. 在Config对象中设置 setCompareName("后裔","狄仁杰")，可以在左上角展示对比图标 76 | 77 | 7. 对比图的效果图如下： 78 | 79 | ![image](https://github.com/luweibin3118/RadarChartView/blob/master/app/Screenshot_20171226-185135.png) 80 | 81 | 8. 如果给Config设置如下参数，可实现雷达图随手势滑动： 82 | 83 | setCanScroll(true) // true表示可以手势滑动 84 | 85 | setCanFling(true) // true表示可以Fling 86 |
