Hi I am using the Trial version of your api in respects of the Chart and Radial Gauge. I am able to get it to work perfectly well on android but on iOS it continually crashes with an "Unhandled Exception: Object Reference cannot be null" when the gauge tries to load. This exception appears in the Application.cs on the "UIApplication.Main(args, null, "AppDelegate");" line.

When I dig deeper I am able to find a Stack Trace that says that the problem is in the Telerik.XamarinForms.SkiaSharp.dll but not exactly what the problem is as this is as much of the stack trace I am able to see:

" at Telerik.XamarinForms.SkiaSharp.SkiaPainter.CanvasPaintSurface (System.Object sender, SkiaSharp…"

 

I am running windows 10 with Visual Studio 2017 installed.

I have a (complex) list view (that also has a drawer). If the user taps on an item in the list they navigate to another page. The user can then go back to the list view. Usually all is fine, but sometimes when they come back it looks like this: http://i.imgur.com/viuxkKS.png. For some reason the list has decided to use only part of the display. This is just a guess, but it might be using the width of the drawer.

Hello,

I'm trying to implement the example custom gauge in my iOS app and everything looks great except that the animation is not working. When I run the example code supplied with the trial package in Xamarin Studio the animation works, however if I put the same code into my app the animation no longer works. Is there a way to troubleshoot this issue? Is there a way to generate an exception that will give me some clue to the cause of the problem?

Thanks.

Hello

We working with the chart in xamarin android 
The horizontal axis is  DateTimeCategoricalAxis
DateTimeComponent = DateTimeComponent.TimeInMillis
LabelFormat = "HH:mm"
LabelFitMode = AxisLabelFitMode.None,


ShowLine=false,
I have some questions:
1.How to hide the ticks
2.When the LabelLayoutMode = AxisLabelLayoutMode.Inner in the vertical axis
There is gap from the left (look in the attached file)
3.I can’t change the label format in the horizontal axis it not working 
4.When the grid adds to the view it fills parent width after I add the series the width is 
Change the there is gap from the right (look in the attached file)

the desired result from the horizontal axis label format is in the attached file 

i cant do this my data is to big and i have 5 deferent series 

public class Converter : Java.Lang.Object, IFunction
    {
        public Java.Lang.Object Apply(Java.Lang.Object p0)
        {
            MajorTickModel tick = (MajorTickModel)p0;

            // Use the collection index to get the correct date from your data.
            // Then you can return the correct string based on that date.
            return tick.CollectionIndex().ToString();
        }
    }

Best Regards

Hello 
We use Chart.AllowTrackball = true;
After track on the chart sometimes the application is crush


Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.
The app has been terminated.
How to handle this crush?
