title: Label above bar not showing for horizontal bars ios-charts
body: <p>I am implementing ios-charts in my project for a horizontal bar chart. I need the values of the individual bars to appear above the bars (since the chart is horizontal, the label should appear on the right of the bar). However, I am unable to make it work. The code is as follows:</p>
  
  <pre><code>func setupHorizontalChartView() {
  
          self.chartView.chartDescription?.enabled = false
          chartView.dragEnabled = false
          chartView.setScaleEnabled(true)
          chartView.pinchZoomEnabled = false
  
          let chartXAxis = chartView.xAxis
          chartXAxis.labelPosition = .bottom
  
          let chartLeftAxis = chartView.leftAxis
          chartLeftAxis.labelFont = NSUIFont(name: "Helvetica", size: 12)!
          chartLeftAxis.labelTextColor = UIColor.darkGray
  
          chartView.rightAxis.enabled = false
  
          chartView.drawValueAboveBarEnabled = true
  
          let formatter = BarChartFormatter()
          formatter.setValues(values: self.months)
  
          chartView.xAxis.valueFormatter = formatter
          chartView.xAxis.setLabelCount(self.months.count - 1, force: false)
  
          chartView.xAxis.drawGridLinesEnabled = false
          chartView.leftAxis.drawGridLinesEnabled = false
  
          chartView.xAxis.drawAxisLineEnabled = false
          chartView.leftAxis.drawAxisLineEnabled = false
  
          chartView.leftAxis.drawLabelsEnabled = false
      }
  
      func setChart(dataPoints: [String], values: [Double]) {
  
          var dataEntries: [BarChartDataEntry] = []
  
          for i in 0..&lt;dataPoints.count {
              let dataEntry = BarChartDataEntry(x: Double(i), y: values[i])
              dataEntries.append(dataEntry)
          }
  
          let chartDataSet = BarChartDataSet(values: dataEntries, label: "Units Sold")
  
          chartDataSet.drawValuesEnabled = true
          let chartData = BarChartData(dataSet: chartDataSet)
          chartData.setDrawValues(true)
  
          chartView.data = chartData
      }
  </code></pre>
  
  <p><code>drawValueAboveBarEnabled</code> has been set to true for the chartView. When I use the same code for BarChartView instead of HorizontalBarChartView, the values of the bars get shown above the bars. However, it doesn't work for horizontal bar chart view.</p>
