Chart Export is black on UWP

[Julien Torrent]

Hi,

When I'm trying to use chart.SaveAsImage("ChartSample.jpg"); on UWP,  the image I get has a black background. It makes the image unreadable.

However on Android and iOS, it export what I see on the screen (White background).

Is it going to be fixed ?

If no, is there a workaround to get what I see on the screen ?

Thanks

Hi Torrent, 

 

Thanks for using Syncfusion products. 

 

We have exported chart as image by using RenderTargetBitmap in UWP. If control background is “Transparent”, then output of control image background will be “Black” in RenderTargetBitmap. However, we can resolve this problem by setting chart Background as White to get white background image as shown in the below code snippets. 

 

Code snippet[Xaml]: 

<chart:SfChart BackgroundColor="White"> 

   . . . 

</chart:SfChart> 

 

Code snippet[C#]: 

chart.BackgroundColor = Color.White; 

 

Please let us know if you need any further assistance.

Hi,

The only problem is when I don't have a title, the last upper label is half black.

The chart white stop at the last horizontal line.

Thanks

Hi Torrent,  

  

We can resolve your problem by setting Margin property for SfChart as per the below code snippet.  

 

Code snippet [XAML]: 

 

<chart:SfChart BackgroundColor="White" Margin="10"> 

 

</chart:SfChart> 

 

 

Code snippet [C#]: 

 

 

chart.Margin = new Thickness(10);
