Before SciChart was created, most chart components used default graphics libraries (provided by the Operating system) to draw charts, which resulted in poor performance when charting more than a few thousand datapoints. While most applications don’t need to show thousands or millions of data-points, some do. When SciChart v1 was created in 2012 there were no WPF Charts in the world which used Hardware Acceleration and most were limited to a few thousand points at most. This meant creating scientific or realtime charting applications was simply impossible.
