Font rendering error on Fedora Linux

Bug Report Template

ScottPlot Version: 4.1.15

Operating System: Fedora 34, Wayland, 64-bit

Application Type: console

Bug Description: The numbers in the chart aren’t rendered correctly:

I installed libgdiplus as described in the README. Do I need to install something in addition to that? I don’t know if a font is missing or something else is going wrong?

Reproducing:

namespace stocks
{
    class Program
    {
        static void Main(string[] args)
        {
            var dataX = new double[] { 1, 2, 3, 4, 5 };
            var dataY = new double[] { 1, 4, 9, 16, 25 };
            var plt = new ScottPlot.Plot();
            plt.AddScatter(dataX, dataY);
            plt.SaveFig("test.png");
        }
    }
}

Thanks for following-up! I’m glad we mostly got this figured out.

Solution

To summarize our findings for future readers, it sounds like manually installing the System.Drawing.Common NuGet package in your project fixed the ScottPlot rendering issue on Linux

Is this a change in v6.0.0 or is it a bug?

It wouldn’t surprise me if this is indeed a change in .NET 6 – it’s the first version they’re specifically stating they don’t support https://docs.microsoft.com/en-us/dotnet/core/compatibility/core-libraries/6.0/system-drawing-common-windows-only
