well... if it's not about highlight, then you have to change the code I guess. Can it be highlight?

@liuxuan30 I think that point may always display red color without any gestures,

and I find my colleague implement it by highcharts, but I have no idea to do it in iOS with our smart Charts, by the way, I don't want to use webview :D

and idea?

thanks for your reply :)

you can create a ChartHighlight object to highlight some bars in code, so you don't have to use gestures, and you have to turn it off. Will you need gestures in the future?

The idea is simple, get touch events -> create ChartHighlight object -> render the highlight

well.. a foolish question, is touch events defined in Utils/ChartPlatform.swift?

I find many swift files which had event method..

thanks for patience ..

[liuxuan30]

touch events handled in BarLineChartViewBase I remember. If it's pie chart, it's in pie chart base

You don't have to handle touches to add highlights. You can just set the highlighted entries...

I implemented it, thanks for your patience :)
