烛台+酒吧的组合图表

Question

在我看来，这似乎是一件非常微不足道的事情，我在Android上工作但不在iOS上工作，即使在以前的问题和以前的问题上阅读相当彻底... ...

无论如何，我只是想创建一个历史价格数据的组合图表，其中包括烛台图表和背景中的音量指示器（条形图）。它显示如下：

代码非常简单，并遵循以下示例：

columns = ['one','two','three','four']
df = pd.DataFrame(sna,columns=columns)
kar = []
[[kar.append(h) for m,h in g.groupby(g['four'] - 
np.arange(g.shape[0])) if len(h) > 1] for k,g in 
df.groupby(df['three'])]

当我删除let set1 = CandleChartDataSet(values: yVals1, label: "Data Set") set1.axisDependency = YAxis.AxisDependency.left set1.setColor(UIColor(white: 80 / 255, alpha: 1)) set1.drawIconsEnabled = false set1.shadowColor = .darkGray set1.shadowWidth = 0.7 set1.decreasingColor = .red set1.decreasingFilled = true set1.increasingColor = UIColor(red: 122 / 255, green: 242 / 255, blue: 84 / 255, alpha: 1) set1.increasingFilled = false set1.neutralColor = .blue set1.drawValuesEnabled = false self.candleStickChartView.xAxis.valueFormatter = IndexAxisValueFormatter(values: xValues) let candleStickData = CandleChartData(dataSet: set1) let data = CombinedChartData() let barChartDataSet = BarChartDataSet(values: barChartEntries, label: "values") barChartDataSet.setColor(UIColor.rhLightGrey().withAlphaComponent(0.3)) barChartDataSet.axisDependency = YAxis.AxisDependency.right let barChartData = BarChartData(dataSet: barChartDataSet) data.candleData = candleStickData data.barData = barChartData self.candleStickChartView.rightAxis.axisMinimum = 0.0 self.candleStickChartView.data = data self.candleStickChartView.setNeedsDisplay() 时，它会显示烛台正常，但我无法获得＆＃34;缩放＆＃34;依赖于烛台值（远低于音量条）。

有什么想法吗？

谢谢！
