Chart shows values as a flat line

[Coca162]

Hi, I am new to making graphs in C# and I thought this library was the best out there!

Right now I am using Microcharts in the following way (assume entries is the example data in the wiki)

var chart = new LineChart { Entries = entries };
SKBitmap bitmap = new(1000, 500);
using SKCanvas canvas = new(bitmap);
chart.Draw(canvas, 1000, 500);
using Stream imageStream = SKImage.FromBitmap(bitmap).Encode().AsStream();

I will then use stream later on

HOWEVER

When I finally see the data I get something like this: BUT if I breakpoint (Visual Studio) before the imageStream is declared I get:

This has driven me a bit insane. I have tried changing the type of chart, width/height, entries and other various things and it has to lead to the same flat line. Is there any way to not make this happen???

Note: To replicate the issue in a simple console application I had to loop this multiple times to get a similar result.

for (int i = 0; i < 10; i++)
{
    //same code as before
    await imageStream.CopyToAsync(File.Create($"{i}.png"));
}

Weirdly image 0 looked like this

I think it's due to the animation. Try to disable it and you'll be able to export the image. On the Chart object set Is animated property to false.
