Try dividing by zero

while (_CameraDataPlot.TryDequeue(out PlotData record))
{
    Parallel.ForEach(record.Values, val =>
    {
        try
        {
            IRenderableSeriesViewModel render = CameraChannels
                .First(x => x.ChannelId == val.Key)
                .RenderableSeries
                .FirstOrDefault(r => (int)(r as LineRenderableSeriesViewModel).Tag == record.Group);

            if (render != null)
            {
                using (render.DataSeries.SuspendUpdates())
                {
                    long ticks = record.Timestamp / 100;
                    (render.DataSeries as XyDataSeries<TimeSpan, double>).Append(new TimeSpan(ticks), val.Value);
                }
            }
        }
        catch (DivideByZeroException ex)
        {
            Console.WriteLine($"DivideByZeroException caught: {ex.Message}");
            Console.WriteLine($"Timestamp: {record.Timestamp}, Value: {val.Value}");
            Console.WriteLine($"Stack Trace: {ex.StackTrace}");
        }
        catch (Exception ex)
        {
            // Optional: Add logging or handling for general exceptions
        }
    });
}

Here is my code. When my frame rate is set to greater than 1, rendering is normal, but when I set the frame rate to less than 1, an error occurs at the “render.DataSeries as XyDataSeries<TimeSpan, double>).Append(new TimeSpan(ticks), val.Value);” position: attempting to divide by 0.

The detailed error message is as follows:
