Diffrent X-axis label color

[amitvyawahare]

Is there any way to use different color for different XAxis data point ? I know we can do this for Y-Axis using chartDataSet.valueColors = valueColors

Is there any similar function for XAxis ?

No, and you have to do it yourself and you are more than welcome to file a PR with a clean design :)
btw, the data set value colors is for the chart value labels, not y axis itself.
x and y axis only support one labelTextColor

If you absolutely have to change the xAxis colors, here is where the magic happens. Although you would have to change it every time you update the code. I found it inside XAxisRendererHorizontalBarChart. I am sure there is something similar for other charts.

if viewPortHandler.isInBoundsY(position.y)
            {
                if let label = xAxis.valueFormatter?.stringForValue(xAxis.entries[i], axis: xAxis)
                {

                    //--vvv--I ADDED THIS CODE---vvv---
                    var color: UIColor!
                    if label == "This String" || label == "That String" || label == "These Strings" {
                        color = UIColor(red: 0/255, green: 64/255, blue: 135/255, alpha: 1/1)
                    } else {
                        color = UIColor(red: 0/255, green: 122/255, blue: 255/255, alpha: 1/1)
                    }

                    drawLabel(
                        context: context,
                        formattedLabel: label,
                        x: pos,
                        y: position.y,
                        attributes: [NSFontAttributeName: labelFont, NSForegroundColorAttributeName: color],
                        anchor: anchor,
                        angleRadians: labelRotationAngleRadians)
                    //--^^^--I ADDED THIS CODE---^^^---

                    //--vvv--OLD CODE---vvv---
//                    drawLabel(
//                        context: context,
//                        formattedLabel: label,
//                        x: pos,
//                        y: position.y,
//                        attributes: [NSFontAttributeName: labelFont, NSForegroundColorAttributeName: labelTextColor],
//                        anchor: anchor,
//                        angleRadians: labelRotationAngleRadians)
                }
            }

I'm considering writing something for this, because I have to familiarize myself with this code so much anyhow for my job. I just need to learn common protocols for contributing to git projects.
