Set the Y axis to a specific Tick Steps

[mrvallejo]

I am trying to setup the specific tick steps to the Y axis. The problem is that I get nil with the aaOptions.yAxis as? AAYAxis and I cannot configure the yAxis steps. Is it a bug?. I am using the last pod version

var passRange = ["+1.00","+0.50","+0.00","-0.50","-1.00"]
var passResult = [0.3,0.1,-0.2,0.5,0.7]

    override func viewDidLoad() {
        super.viewDidLoad()
        let aaChartView = createChart(view: plotView)
        let aaOptions = customOptions()
        aaChartView.aa_drawChartWithChartOptions(aaOptions)
    }
    
    func createChart(view:UIView)-> AAChartView{
        let aaChartView = AAChartView()
        aaChartView.frame = CGRect(x:0,y:0,width:view.layer.frame.width,height:view.layer.frame.height)
        view.addSubview(aaChartView)
        return aaChartView
    }
    
    private func customOptions() -> AAOptions {
        
        let aaChartModel = AAChartModel()
            .chartType(.line)
            .colorsTheme(["#1e90ff","#ef476f","#ffd066","#04d69f","#25547c",])
                .axesTextColor(AAColor.white)
                .title("")
                .subtitle("")
                .dataLabelsEnabled(true)
                .tooltipValueSuffix("")/
                .animationType(.bounce)
                .backgroundColor("#22324c")
                .touchEventEnabled(true)
                .categories(passRange)
                .yAxisReversed(true)
                .yAxisMin(-0.2)
                .yAxisMax(1)
            
                .series([
                    AASeriesElement()
                        .name("")
                        .data(passResult)
                        ,
                    ])
        
           
        let aaOptions = AAOptionsConstructor.configureAAOptions(aaChartModel: aaChartModel)

        let aaYAxis = aaOptions.yAxis as? AAYAxis
        aaYAxis?.tickPositions([-0.2,-0.1,0,0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1.0])
         return aaOptions
    }

Without any changes, I finally got the AAYAxis object instance and the tickPositions value using your code.

Maybe there is something wrong with your project.

First, thanks for your fast answer and congratulations for your work, it is quite good. I have reproduced the bug in a project.

• If the chart is attached to the self.view of the view controller the chart is properly configured

• If the chart is attached to a view from the storyboard, it returns nil. I am using Xcode
