JBBarChartView does not display all the bars

[nikalra]

I tried setting up a tests class with a bar graph but on iOS 8.1, it seems that one of the bars is missing/not displayed (image below). This happens in both the Simulator and on the iPhone.

I've also copied all of my code below.

Thanks!

import UIKit
import JBChart

class FirstViewController: UIViewController, JBBarChartViewDelegate, JBBarChartViewDataSource {

    var barChartView: JBBarChartView?
    var chartLegend = ["11-14", "11-15", "11-16", "11-17", "11-18", "11-19", "11-20"]
    var chartData = [70, 80.0, 76, 88, 90, 69, 74]

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        barChartView = JBBarChartView()
        barChartView!.frame = CGRectMake(20, 20, self.view.bounds.width - 40, self.view.bounds.height * 0.5)
        barChartView!.backgroundColor = UIColor.darkGrayColor()
        barChartView!.delegate = self
        barChartView!.dataSource = self
        view.addSubview(barChartView!)

        var footerView = FooterView()
        footerView.leftLabel.text = chartLegend[0];
        footerView.rightLabel.text = chartLegend[chartLegend.count - 1 ];
        barChartView!.footerView = footerView

        barChartView!.reloadData()

    }

    override func viewDidAppear(animated: Bool) {
        super.viewDidAppear(animated)

        view.setNeedsLayout()
        barChartView!.reloadData()
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


    // MARK: JBBarChartView

    func numberOfBarsInBarChartView(barChartView: JBBarChartView!) -> UInt {
        return UInt(chartData.count)
    }

    func barChartView(barChartView: JBBarChartView!, heightForBarViewAtIndex index: UInt) -> CGFloat {
        let height = CGFloat(chartData[Int(index)])
        println("Index: \(index); Height: \(height)")
        return height
    }

    func barChartView(barChartView: JBBarChartView!, colorForBarViewAtIndex index: UInt) -> UIColor! {
        println("Color for index \(index)")
        return (index % 2 == 0) ? UIColor.greenColor() : UIColor.blueColor()
    }

Set:

barChartView.minimumValue = 0.0f;

the normalisation issue - smallest value looks like empty. I added a 0 value entry at the end. worked great , too.

Hi DirkLXX,
any chance you can elaborate on adding a 0 value entry at the end? Did you add that to the array that acts as the datasource for the chart? For me this just seems to place the blank bar (corresponding to the smallest value in the array) at the end. Thoughts? Thank you so much in advance.
