Question

我正在尝试使用500值为我的应用绘制类似于我的应用程序的正态分布图的Area图，我进入了这个https://github.com/danielgindi/Charts，但是它并未正确显示，它只显示了图的一部分如果有人可以告诉我我在做什么错了，那是我的代码

    func updateGraph(line: LineChartView,
                     prices xs: [Double],
                     fit ys: [Double])
    {
        var lineChartEntry  = [ChartDataEntry]()

        for i in 0..<xs.count {

            let value = ChartDataEntry(x: xs[i], y: ys[i])
            lineChartEntry.append(value)
        }
        let lineDataSet = LineChartDataSet(values: lineChartEntry, label: "Probability")
        lineDataSet.colors = [UIColor.blue]
        lineDataSet.drawCirclesEnabled = false
        lineDataSet.drawValuesEnabled = false
        lineDataSet.drawFilledEnabled = true
        lineDataSet.fillColor = UIColor.blue
        lineDataSet.fillAlpha = 0.9
        let data = LineChartData()
        data.addDataSet(lineDataSet)
        line.data = data
        line.chartDescription?.text = "Monte Carlo Simulation"
        line.backgroundColor = UIColor.clear
        line.chartDescription?.textColor = UIColor.blue
        line.xAxis.labelTextColor = UIColor.blue
        line.gridBackgroundColor = NSUIColor.blue
        line.animate(xAxisDuration: 1, yAxisDuration: 1)
    }

This is the output graph

While this is the expected output (showed once in many runs)

iOS-图表lineFilled无法正常工作
