Blurry when printing livechart2

[Rkjena10]

Hello,

I am using Livechart2 in WPF. I want to print the the Cartesian chart. I didn't find the print document how it was working earlier for C# WinForms Data Visualization chart because here it looks very clear. So , in wpf i rendered the chart into Bitmap then i print this. But the chart is not at all clear , its blurry. Is there any solution without using Bitmap ? I used below code to convert the UIElement into Bitmap. I need to make the Chart looks clear in print document.

**_public static Bitmap ConvertUIElementToBitmap(UIElement element)
{
double width = element.RenderSize.Width;
double height = element.RenderSize.Height;

        double cropTop = 45; 
        double croppedHeight = height - cropTop;  

      
        if (croppedHeight <= 0)
        {
            throw new ArgumentException("Crop height is too small, adjust cropTop accordingly.");
        }

        var source = PresentationSource.FromVisual(element);
        double dpiX = 96;  
        double dpiY = 96;

        if (source != null)
        {
            dpiX = source.CompositionTarget.TransformToDevice.M11 * 96; 
            dpiY = source.CompositionTarget.TransformToDevice.M22 * 96; 
        }
        RenderTargetBitmap renderBitmap = new RenderTargetBitmap(
            (int)width,
            (int)croppedHeight,
            dpiX,
            dpiY,
            PixelFormats.Pbgra32);

        DrawingVisual drawingVisual = new DrawingVisual();

        using (DrawingContext dc = drawingVisual.RenderOpen())
        {
            dc.DrawRectangle(System.Windows.Media. Brushes.White, null, new Rect(0, 0, width, croppedHeight));
            dc.DrawRectangle(new VisualBrush(element), null, new Rect(0, -cropTop, width, height));
        }

        renderBitmap.Render(drawingVisual);

        return ConvertToDrawingBitmap(renderBitmap);
    }_**
    
    Any idea ? Please help.
