\SampleCode\DynamicChart 报错提示如上。请问什么原因

Answer 1

您好，看报错信息是因为找不到PieChart这个类，请问一下您那边添加了哪些jar包呢？是否有添加com.github.mikephil.charts.jar，使用此功能需要这个jar包的

Comments

可以了。缺少 com.github.mikephil.charts.jar chartengine.jar   MPChart 和 achartengine的两个依赖包。超图的图表是依赖他们做的开发

---

PieChart.clear();

每次创建饼图 只有图例刷新，图表clear但不刷新什么原因？

---

能否问下怎么添加依赖包的，是在网上下载吗？我百度不到
