We’d like to customize the look of our legends. We have 4 legends displaying different data, but right now the only thing we can change is the Theme. Is there any way to customize the legend items, like add some icons, change the point marker shape and size, change the check box icon etc…

P.S.: I’m not a trial user. We have an iOS, Android and WPF licenses purchased.

Project info:
Xamarin.iOS
SciChart.iOS 2.2.2.854

We’re trying to make multiple legends on the screen, for example, 1 for the left axis and its data series, 1 for the right axis and its data series. I can see it’s possible in the WPF documentation, but in the iOS documentation it says “Coming soon!”. Do we need to wait for a future release of the Xamarin.iOS library or is it possible somehow now?

By the way, I’m not a trial user. We’ve just purchased a license today.

Thanks,
Lazar Nikolov

Dear Support, I have SciChartSurface in fragment (Xamarin Android). I added Xaxis (DateAxis), Yaxis (NumericAxis), standard modifiers and few XyDataSeries as FastLineRenderableSeries. Everything is working fine (screenshot 1). But something strange is happen when fragment with chart is Paused -> Stopped and then Started -> Resumed. Xaxis and Yaxis are not visible. All dataseries are not visible. But I debugged and all data is there. Even rolloverModifier is still working and correct data values are displayed in labels (screenshot 2). It does not happen every time – it depends on what external intent stopped fragment.

I’ve tried reinitialize chart (clear Xaxis, Yaxis, remove modifiers, remove renderableSeries are reinit all with new variables) and it does not help. Only fragment dettach -> attach helps or screen orientantion change (it reinitializes fragment)

Could you tell me any suggestion what can I check or how to force to redraw whole SciChartSurface? (hiding it and showing it does not help – effect is the same. Only fragment dettach and attach helps (this is my workaround at the moment).

Hi

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!

Best regards
Jonas

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.

Hi

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 5.1.0.11405 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.
https://medium.com/@SicknoteSteve/nuget-targeting-both-net-standard-and-the-net-framework-326a16266ca4
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="2.5.0.280555" />
</ItemGroup>

<ItemGroup Condition="'$(TargetFramework)' == 'net461'">
  <PackageReference Include="SciChart" Version="5.1.0.11405" />
  <PackageReference Include="Xamarin.Forms" Version="2.5.0.280555" />
</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’ve been pouring through the documentation and examples and cannot find an example of this. Has anyone been able to accomplish this and willing to share an example? Thanks.

Hi,

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.

MainActivity_P.java:50: error: isAttached() in MainActivity_P cannot override isAttached() in PaletteProviderBase
    public boolean isAttached ()
                   ^
    overridden method is final



 MainActivity_P.java:58: error: attachTo(IServiceContainer) in MainActivity_P cannot override attachTo(IServiceContainer) in       PaletteProviderBase
    public void attachTo (com.scichart.core.IServiceContainer p0)
                ^
    overridden method is final



MainActivity_P.java:66: error: detach() in MainActivity_P cannot override detach() in PaletteProviderBase
    public void detach ()
                ^
    overridden method is fina

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?

Trying to install SciChart.iOS NuGet package for Xamarin.iOS project results the following error:

Package SciChart.iOS 2.0.1.527 is not compatible with xamarinios10 (Xamarin.iOS,Version=v1.0). Package SciChart.iOS 2.0.1.527 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.

Hi,

I found this through the forum:
https://www.scichart.com/scichart-2014-the-vision/

Seems you looked at Xamarin at one time or another, is there a plan to support this platform at some point in the future?

Thank you.
