是否可以在图表视图中隐藏图块的颜色

Question

我正在使用 danielgindi 图表库，我想隐藏下面所附图表视图图像一角的图块

我尝试并管理了 o 通过设置空字符串来隐藏字符串，但找不到隐藏磁贴的选项使用以下代码创建的图表

 func setChartNew() {
        //barChartViewShow is uiview with barchartview as file's owner which means in storyboard changed class to barchartview
        barChartViewShow.noDataText = "You need to provide data for the chart."
        
        var dataEntries4: [BarChartDataEntry] = []
              
           for i in 0..<self.cashArray.count  {
               print(Double(self.cashArray[i]) ?? 0.0)
 
               let dataEntry = BarChartDataEntry(x: Double(i) , y: Double(self.cashArray[i]) ?? 0.0)
               dataEntries.append(dataEntry)

               let dataEntry1 = BarChartDataEntry(x: Double(i) , y: Double(self.cardArray[i]) ?? 0.0)
               dataEntries1.append(dataEntry1)

               let dataEntry2 = BarChartDataEntry(x: Double(i) , y:  Double(self.applePayArray[i]) ?? 0.0)
               dataEntries2.append(dataEntry2)
               let dataEntry3 = BarChartDataEntry(x: Double(i) , y:  Double(self.googlePayArray[i]) ?? 0.0)
               dataEntries3.append(dataEntry3)
           }
 //here i have hidden the texts applepay,googlepay,cash,card //
         chartDataSet = BarChartDataSet(entries: dataEntries, label: "")
         chartDataSet1 = BarChartDataSet(entries: dataEntries1, label: "")
         chartDataSet2 = BarChartDataSet(entries: dataEntries2, label: "")
         chartDataSet3 = BarChartDataSet(entries: dataEntries3, label: "")
  //here i have hidden the texts applepay,googlepay,cash,card //
        /*values above bar disabled*/
        chartDataSet.drawValuesEnabled = false
        chartDataSet1.drawValuesEnabled = false
        chartDataSet2.drawValuesEnabled = false
        chartDataSet3.drawValuesEnabled = false
          /*values above bar disabled*/
/*set colors for bars and assign to dataset to display bars*/
           let dataSets: [BarChartDataSet] = [chartDataSet,chartDataSet1,chartDataSet2,chartDataSet3]

chartDataSet2.colors = [UIColor(red: 1/255, green: 192/255, blue: 112/255, alpha: 1)] // 1, 192, 112 applePay
 chartDataSet3.colors = [UIColor(red: 75/255, green: 192/255, blue: 192/255, alpha: 1)] //75, 192, 192 googlePay
        chartDataSet1.colors = [UIColor(red: 249/255, green: 164/255, blue: 26/255, alpha: 1)]  //249, 164, 26 card
        chartDataSet.colors = [UIColor(red: 241/255, green: 96/255, blue: 44/255, alpha: 1)] //241, 96, 44 cash
        chartDataSet.highlightColor = .black

            let chartData = BarChartData(dataSets: dataSets)
         let groupSpace = 0.200
        let barSpace = 0.06
        let barWidth = 0.142
             let groupCount = self.days.count
            let axisMinimum = 0

            chartData.barWidth = barWidth;
        barChartViewShow.xAxis.axisMinimum = Double(startYear)
            let gg = chartData.groupWidth(groupSpace: groupSpace, barSpace: barSpace)
            
        barChartViewShow.xAxis.axisMaximum = Double(axisMinimum) + gg * Double(groupCount)

            chartData.groupBars(fromX: Double(axisMinimum), groupSpace: groupSpace, barSpace: barSpace)
         barChartViewShow.notifyDataSetChanged()

        barChartViewShow.data = chartData
 
        barChartViewShow.backgroundColor = UIColor .white

            //chart animation
        barChartViewShow.animate(xAxisDuration: 1.5, yAxisDuration: 1.5, easingOption: .easeOutSine)
       
        }

其中标签是字符串值但我无法隐藏上面的图块图像请指导我隐藏图表中的图块

Answer 1

您可以在setChartNew()中disable如下图例。一旦你 disable 图例，它就不会再显示在图表中。

let legend = barChartViewShow.legend
legend.enabled = false
