I am developing a Xamarin iOS application and I’m using a SCIPieChartSurface. I can create the chart and set its values, but is is not possible to auto-update the donut with new data.
I am trying to update the value by doing:
myDonut.MyPieSegment.Value = newValue;
But nothing happends…
I heard it was a bug in the API for Android a month ago, is this similar? Or am I doing something wrong?
Thanks in advance!
In Xamarin.IOS when you set the legend to Horizontal and Top it will create a legend at the top then allow you to scroll horizontally to see all your LineSeries. In Xamarin.Android when you have more Series than can originally fit on the screen, the legend malfunctions and takes up the entire screen. Picture will be attached.
When i go to zoom on my YAxis while a YAxis VisibleRangeLimit is baing set, the zoom does not work correctly. Once the zooming is finished it will reset back to the range limit. If i remove the range limit, the zooming then works as expected.
I’m trying to use SciChart in my Xamarin Visual Studio Cross platform application. After installing the SciChart package in the Package Manager console I got the dependency reference error:
Package SciChart 220.127.116.1105 was restored using '.NETFramework, Version=v4.6.1' instead of the project target framework 'NETStandard,Version=v2.0'. This papckage may not be fully compatible with your project .
I know that .NET framework 4.6.1 is different from .NETStandard2.0.
I’ve read some articles about how to target multiple .NET versions in the same application by modifying the .csproj file, but I can’t get it work anyway.
I’ve modified the csproj file like this
<PropertyGroup> <TargetFrameworks>netstandard2.0;net461</TargetFrameworks> </PropertyGroup> <ItemGroup Condition="'$(TargetFramework)'=='netstandard2.0'"> <PackageReference Include="Xamarin.Forms" Version="18.104.22.1680555" /> </ItemGroup> <ItemGroup Condition="'$(TargetFramework)' == 'net461'"> <PackageReference Include="SciChart" Version="22.214.171.12405" /> <PackageReference Include="Xamarin.Forms" Version="126.96.36.1990555" /> </ItemGroup>
This action removes all dependency errors, but I still can’t use the libraries.
Does anyone know how to solve this issue?
Thanks in advance!
I’m trying to wrap the Scichart surface in XF. I’ve used native views as recommended in documentation and there is no problem when the SciChartSurface is the only element in a ContentPage, but when the surface is placed inside a layout or merged with any other element, then is not rendering.
Do you know why is this happening and how can I merge XF controls and SciChartSurface(s) in a ContentPage or any Layout?
1: This is rendering without problem
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" xmlns:local="clr-namespace:SciChartForms" xmlns:localAndroid="clr-namespace:SciChartForms.Droid" x:Class="SciChartForms.MainPage"> <localAndroid:Stripchart /> </ContentPage>
2: This is not rendering:
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" xmlns:local="clr-namespace:SciChartForms" xmlns:localAndroid="clr-namespace:SciChartForms.Droid" x:Class="SciChartForms.MainPage"> <StackLayout Margin="20"> <Button Text="adafsd"/> <localAndroid:Stripchart/> </StackLayout> </ContentPage>
Thanks in advance!
PS: I’ve also tried with custom renderer obtaining the same result.
There’s a build error when implementing IPointMarkerPaletteProvider, IFillPaletteProvider, or IStrokePaletteProvider.

What’s wrong with it? See the attached project to reproduce the issue.
How to achieve per-point shapes? I need to have, say, triangle, ellipse, and square shapes on a single line series. It’s pretty straightforward for iOS by overriding the StyleForPoint() method and providing shapes and colors. However, I had hard times figuring it out for Android (Xamarin). I found how to change colors of markers but not shapes. Could anyone help me with this, please?
I am using SCICHART in my project on Xamarin.Android, but the default them show some themes but I would like to change the background grid color of the reports. Please any can help me ?.
Trying to install SciChart.iOS NuGet package for Xamarin.iOS project results the following error:
Package SciChart.iOS 188.8.131.527 is not compatible with xamarinios10 (Xamarin.iOS,Version=v1.0). Package SciChart.iOS 184.108.40.2067 supports: xamarinios (xamarin-ios,Version=v0.0)
Wondering what the heck is “xamarin-ios,Version=v0.0”? It must be xamarinios10. We’re considering to buy SciChart but right now our build server is stuck on this error. As a workaround, we raname xamarin-ios to xamarinios10 in the lib directory but this not an option for a cloud build server.
I found this through the forum:
Seems you looked at Xamarin at one time or another, is there a plan to support this platform at some point in the future?
