New Post: Draw annotation with 3600*10 datapoints

Modified Performance Example in sample examples, found it is hard to handle random data.
Instead of drawing sin cos data, I tested with Random data.

In Example_Browser->PerformanceExamples.cs
Plot freeze.

I believe it is WPF's limit.

private static void AddPoints(IList<IDataPoint> points, int n)
        {
            //for (int i = 0; i < n; i++)
            //{
            //    double x = Math.PI * 10 * i / (n - 1);
            //    points.Add(new DataPoint(x * Math.Cos(x), x * Math.Sin(x)));
            //}

            int dataCounts=n;
            var rnd = new Random();
            for (int i = 0; i < dataCounts; i++) {
                var dp = new DataPoint(i, rnd.Next(0, 65000));
                points.Add(dp);
            }

        }
