Attributes of text above specific bar with ios-charts
To set your own colors/font you can use properties valueColors and 'valueFont' of BarChartDataSet class
So it'll be something like this
...var valueColors = [UIColor]()// dataEntries and barChartDataSetvar dataEntries = [ChartDataEntry]()for i in 0..<dataPoints.count{ let dataEntry = BarChartDataEntry(value: values[i], xIndex: i) dataEntries.append(dataEntry) if values[i] < 0 { valueColors.append(UIColor.redColor()) } else { valueColors.append(UIColor.greenColor()) }}let barChartDataSet = BarChartDataSet(yVals: dataEntries, label: "")barChartDataSet.colors = colorsbarChartDataSet.valueColors = valueColorsbarChartDataSet.valueFont = *font you want*
If you want to change the text attributes of labels below bars you can use:
barChartView.xAxis.labelFont = UIFont.systemFont(ofSize: 5)
barChartView.xAxis.labelTextColor = UIColor.red
