iOS图表Xcode中的LineGraph不显示所有值。为什么？

我在我迅速xcodeproject使用的是iOS Charts.framework（https://github.com/danielgindi/Charts）。我的X值是日期为字符串和我的Y衣被合计为0和1000之间的双数据我的测试数据系列的尺寸是392，它有值大于0.0，超过20位，但其他日期的值是0.0（如见下面的valueArray）。 LineChart图只显示5个值> 0.0的值（如下图所示）。为什么？是否可以让LineChart显示所有值？或者我应该使用不同的图表库？iOS图表Xcode中的LineGraph不显示所有值。为什么？

这里是在该阵列中显示以下

这并没有帮助。是的，但是......好吧，我认为这张图表可以显示超过前30个值！ Maby Im使用错误的框架... – ia17

您需要将以下代码添加到项目中这解决了你的显示标签问题。

 for (id<IChartDataSet> set in chartView.data.dataSets) 
     { 
      set.drawValuesEnabled = !set.isDrawValuesEnabled; 
     } 

     [chartView setNeedsDisplay];
