Chart auto min/max does not take into account second line

[A1exandre]

Hi,

I have a custom LineChartView, with two lines and I use self.leftAxis.resetCustomAxisMax() and Min().
However, I've noticed that if a min or a max is in the second line, it is not taken into account by the auto max/min of the chart.

Here's how my code is setup:

self.data = FirstLineDataSet
self.data.addDataSet(secondLineDataSet)

then I set all the chart's settings, including calling resetCustomAxisMax

 self.backgroundColor = UIColor(white: 0, alpha:0)
        self.leftAxis.removeAllLimitLines()
        self.rightAxis.removeAllLimitLines()
        self.leftAxis.enabled = true
        self.rightAxis.enabled = false

        self.xAxis.labelFont = UIFont(name: "Bariol", size: 10)!
        self.gridBackgroundColor = UIColor(white: 0, alpha:0)
        self.noDataText = ""

        self.leftAxis.labelPosition = .OutsideChart
        self.leftAxis.drawLabelsEnabled = false
        self.leftAxis.drawAxisLineEnabled = false
        self.leftAxis.enabled = true

        self.xAxis.enabled = true
        self.xAxis.drawAxisLineEnabled = true

        self.legend.enabled = false
        self.descriptionText = ""
        self.backgroundColor = UIColor(white:0, alpha:0)

        self.xAxis.drawAxisLineEnabled = false
        self.xAxis.drawGridLinesEnabled = false
        self.xAxis.labelPosition = .Bottom

            self.pinchZoomEnabled = false
        self.doubleTapToZoomEnabled = false
        self.dragEnabled = false
        self.drawMarkers = false


        self.xAxis.avoidFirstLastClippingEnabled = true
        self.extraLeftOffset = 15
        self.extraRightOffset = 15

        self.leftAxis.resetCustomAxisMax()
        self.leftAxis.resetCustomAxisMin()
