Multiple Highlight points

[llKoull]

Hi!

I'm using this awesome library to represent 2 line charts using the same LineChartView.

Is it possible to show the highlight point simultaneously in both lines? It does not mind me if the highlight points are going to be in the same X value at the same time or not (the X values are the same for both lines).

Thanks and best regards,

Hello @llKoull
Renderer supports this.
LineChart2ViewController from examples:

    override func chartValueSelected(_ chartView: ChartViewBase, entry: ChartDataEntry, highlight: Highlight) {
        super.chartValueSelected(chartView, entry: entry, highlight: highlight)

        var secondSetIndex: Int
        if highlight.dataSetIndex == 0
        {
            secondSetIndex = 2 //the second (index == 1) set is red, the selection is not visible enough
        }
        else
        {
            secondSetIndex = 0
        }
        let secondHighlight = Highlight(x: highlight.x, y: highlight.y, dataSetIndex: secondSetIndex, dataIndex: highlight.dataIndex)

        chartView.highlightValues([highlight, secondHighlight])

        self.chartView.centerViewToAnimated(xValue: entry.x, yValue: entry.y,
                                            axis: self.chartView.data!.getDataSetByIndex(highlight.dataSetIndex).axisDependency,
                                            duration: 1)
        //[_chartView moveViewToAnimatedWithXValue:entry.x yValue:entry.y axis:[_chartView.data getDataSetByIndex:dataSetIndex].axisDependency duration:1.0];
        //[_chartView zoomAndCenterViewAnimatedWithScaleX:1.8 scaleY:1.8 xValue:entry.x yValue:entry.y axis:[_chartView.data getDataSetByIndex:dataSetIndex].axisDependency duration:1.0];
    }

Hello @bivant !

Thanks for your quick answer i didn't see the method highlightValues!! I'm using it now and it's working perfectly.
