SciChart® the market leader in Fast WPF Charts, WPF 3D Charts, and now iOS Charting & Android Chart Components
The speed is incredible. When our company was looking for a new Chart provider I tested at least 10 providers. No one even came close at all to what I saw with SciChart. I created a sample which I sent to several competitors and asked them to alter it for their chart to improve the performance, and even with that no one could touch SciChart.
