Swift ios-charts Set Bar Color on Highlight

Question

Within the ios-charts delegate method:

@objc func chartValueSelected(chartView: ChartViewBase, entry: ChartDataEntry, dataSetIndex: Int, highlight: ChartHighlight) { }

I would like to change the color of the bar that was selected. Is this possible?

Ah, on the set. You're right, sorry for the silly question, I don't know much of the ios-charts framework yet. Feel free to post as an answer if you want — Connor Neville, Feb 28 '16 at 21:06

You can change the color for highlights using:

highlightColor

on the chart data set.

The problem with ios-charts is that they don't have a good documentation and they link only to the Android documentation and some of the variables/methods are not very programmer friendly because they were translated from the Android version and don't really follow Swift naming conventions.

If you are looking for something, just open the source code for the given chart or its renderer.

some color is getting mixed into the color. As I am setting it as yellow and it is giving me parrot-green color – Shubham Ojha Apr 20 '20 at 04:36

You can change highlightColor and highlightAlpha on the chart data set.
