使用图表

Question

您好我在使用图表库并且我已经构建了一些图表，但是我想用PieChart做一些特别的事情但我不能这样做但我不会知道哪些可能是像y想要设置我的饼图的属性。好的，我想为图表设置一个最大值为100，通过设置这个，我想我的图表只显示我试图在这种情况下显示的数字es 50和其他部分图应该看起来是空的。我希望你能帮助我。

This is what I have now the graph has just one Double value that value is 50

This is the way that the graph should look like

 func createPieGraphRedemptions() {
        var chart = PieChartView()
        chart = PieChartView(frame: CGRect(x: 229, y: 40, width: 165, height: 165))
        let yVals: [Double] = [50]
        var entries = [ ChartDataEntry]()
        for (i, v) in yVals.enumerated() {
            let entry = ChartDataEntry()
            entry.x = Double( i)
            entry.y = v

            entries.append( entry)
        }
        let set = PieChartDataSet( values: entries, label: "Pie Chart")

        set.colors = [UIColor.red]

        let data = PieChartData( dataSet: set)
        //data.setDrawValues(false)
        chart.data = data
        chart.noDataText = "No hay datos disponibles"
        chart.isUserInteractionEnabled = false
        chart.legend.enabled = false
        chart.chartDescription?.text = ""
        chart.highlighter = nil



        self.view.addSubview(chart)
    }
