Xamarin IOS Chart

Question

I am trying to build a chart using the library described in this post from xamarin forum
https://forums.xamarin.com/discussion/105647/ioscharts-xamarin-implementations

but i cant really render any graphics so far, anyone knows how to do that?

public override void ViewDidLoad()
        {
            base.ViewDidLoad();
            var tmp = new iOSCharts.BarChartView();
            var data = new BarChartData();
            data.AddEntry(new ChartDataEntry(1,1), 1);
            tmp.Data = data;
            tmp.BackgroundColor = UIColor.Red;
            tmp.ChartDescription.Text = "eeeee";

            Test.AddSubview(tmp);

            // Perform any additional setup after loading the view, typically from a nib.
        }

Hello,

Welcome to Microsoft Q&A!

Take a look at this elegant chart plugin : Microcharts .

First install Microcharts package in your ios project, then call the api .

The usage is pretty simple as below .

   var entries = new[]  
   {  
       new ChartEntry(212)  
       {  
           Label = "UWP",  
           ValueLabel = "112",  
           Color = SKColor.Parse("#2c3e50")  
       },  
       new ChartEntry(248)  
       {  
           Label = "Android",  
           ValueLabel = "648",  
           Color = SKColor.Parse("#77d065")  
       },  
       new ChartEntry(128)  
       {  
           Label = "iOS",  
           ValueLabel = "428",  
           Color = SKColor.Parse("#b455b6")  
       },  
       new ChartEntry(514)  
       {  
           Label = "Forms",  
           ValueLabel = "214",  
           Color = SKColor.Parse("#3498db")  
       }  
   };  
     
               var chart = new LineChart { Entries = entries };  
     
               var chartView = new ChartView  
               {  
                   Frame = new CGRect(0, 0, View.Bounds.Width, 250),  
                   AutoresizingMask = UIViewAutoresizing.FlexibleWidth,  
                   Chart = chart  
               };  
     
               View.AddSubview(chartView);  

Thank you.
