Question

我想在我的Android应用程序中使用工具提示功能显示堆积条形图。我用MarkerView显示它但没有成功。这是示例代码。

此外，我在传奇中遇到问题......！由于图书馆不支持文本换行，因此图例不会显示。并且Y轴上的值显示在整数中。我希望在Floats中显示。我可以在Y轴值中给出'％'吗？像这样的东西，

Answer 1

新的mpAndroidChart v2.0.7库解决了所有问题。使用.setValueFormatter（）;我们可以格式化Y轴值和图表值。

对于传奇问题，我没有显示Legends，而是添加了Touch Listener，它可以处理堆栈值。触摸监听器可以显示有价值的细节。
