Description
TDownSamplingFunction may be added to your project by Chart Editor at design time or at runtime using code.
It uses an algorithm with which polylines consisting of many points can be reduced to a simplified form. This can be useful in situations where your graphical application must draw many polylines and time becomes an issue, like cartographic applications.
Default period for TDownSamplingFunction is 1.
TDownSamplingFunction will work only with a single series as datasource.
The DataSource can be defined using the Chart Editor or through code.
