Coca Pod Chart Not Appearing (Swift4)

coca pod Chart not appearing (Swift4)

Try this one it's is Working (Swift 4 Code).

import UIKit
import Charts

class RootViewController: UIViewController {

@IBOutlet weak var lineChartView: BarChartView!

var days: [String]!

    override func viewDidLoad() {
         super.viewDidLoad()

         days = ["Monday","Tuesday","Wednesday","Thursday"]
         let task = [1.0,4.0,3.0,5.0]
         setChart(dataPoints: days, values: task)     
    }

    func setChart(dataPoints : [String], values : [Double]){

       lineChartView.noDataText = "Nothining to display"
       var dataEntries : [BarChartDataEntry] = []
       var counter = 0.0

       for i in 0..<dataPoints.count {
            counter += 1
            let dataEntery = BarChartDataEntry(x: counter, y:values[i], data: days as AnyObject)
            dataEntries.append(dataEntery)
       }

       let ChartDataSet = BarChartDataSet(values: dataEntries, label: "Time")
       let chartData = BarChartData()
       chartData.addDataSet(ChartDataSet)
       lineChartView.data = chartData
       ChartDataSet.colors = ChartColorTemplates.joyful()
       lineChartView.animate(xAxisDuration: 2.0, yAxisDuration: 2.0)

   }
}

Output is :

Modify Graph Hide and Show Axis and Labels

lineChartView.leftAxis.drawLabelsEnabled = false // Hide Left Axis Label
lineChartView.rightAxis.drawLabelsEnabled = false // Hide Right Axis Label
lineChartView.xAxis.drawLabelsEnabled = false // Hide Top Axis Label

lineChartView.leftAxis.enabled = false // Hide Left Axis Lines
lineChartView.rightAxis.enabled = false // Hide Right Axis Lines      
lineChartView.xAxis.enabled = false // Hide Right Axis Lines

lineChartView.legend.enabled = false //Hide Legend of Chart

lineChartView.chartDescription?.text = "" // Hide or Change Chart Description text

iOS Charts not showing Y values

You should add data.setDrawValues(true) when you create the BarChartData:

...
let data = BarChartData(dataSet: barChartDataSet)
data.setDrawValues(true)
data.setValueFont(UIFont(name:"Lato-Regular", size:10)!)
data.setValueTextColor(UIColor(hex:UIConstants.Graphics.BrandTheme.ThemeColor))
...

For version 3.2.1 of Charts you also need to remove this line because values are not rendered if drawIconsEnabled is false

barChartDataSet.drawIconsEnabled = false

Swift charts not showing value labels

Figured it out. Turns out, when you create a data set using an array of ChartDataEntry objects, the array must be immutable (let rather than var), or labels will not be shown.

iOS Charts no longer work after Xcode and Swift Update

Here is what I suggest looking at first

1. The Swift Version setting of Charts is set to Swift 4.
2. If you have a .swift-version file under your project, make sure the content of it is "4.0".
3. Try to clean your project.

If you go to the project navigator and click you project. Under targets, select the target you want to modify. Click build settings for that target. Under Swift Compiler - Language, change swift language version to swift 4.0. Clean and restart xcode

In your pod file, make sure that each target is using the correct swift language version.

See this screenshot for the charts sample project - pods file

This is for the project file

Line Chart in swift 3

A hint for how you can figure out the overloads and I use all the time. In the "Find Navigator" in xCode you can search for "class LineChartData" -- then you can go examine the code in your pod where the "LineChartData" class is defined and see what arguments are in its init methods. Anyway, the answer I believe, base on this would be to change the line where you say:

 let data: LineChartData = LineChartData(xVals: months, dataSets: dataSets)

to THIS

 let data: LineChartData = LineChartData(dataSets: dataSets)

This matches the available overloads. If too late for you, above may help somebody else.

Right way to add Charts with cocoapods

With help of Scott Thompson, I've found that

pod 'Charts', '3.6.0'

is worked and there are no error at build time! So, I think this is the right solution.
