LineChart 避免绘制 0 值

Question

我正在使用 https://github.com/danielgindi/Charts 库。我试图从图表中删除 0 个值，但无法找到特定的解决方案，我们将不胜感激。 yAxis 的值类型为 Double 当前显示的图表：

更新折线图如我所愿

 var dataEntries: [ChartDataEntry] = []
        
 for i in 0..<forX.count {
            
   let dataEntry = ChartDataEntry(x: Double(i), y: forY[i])
   print(dataEntry)
   dataEntries.append(dataEntry)
           
}
        
let lineChartDataSet = LineChartDataSet(entries: dataEntries, label: "")
      
let lineChartData = LineChartData(dataSet: lineChartDataSet)
chart.data = lineChartData

Answer 1

只是不要将它添加到您的数据条目中

for i in 0..<forX.count {
   if forY[i] != 0 {
       let dataEntry = ChartDataEntry(x: Double(i), y: forY[i])
       print(dataEntry)
       dataEntries.append(dataEntry)
   }
}
