hi,
i need to write some line simplification code (ex. https://en.wikipedi
a.org/wiki/Ramer%E2%80%93Douglas%E2%80%93Peucker_algorithm ).
i was wondering how line simplification is achieved in TAChart.
i am interested in how from N point to leave only n points with least
degradation of the theoretical curve.
thank you

This algorithm is not available within TAChart. Of course you can use
TAChart to plot the initial and final curves, but the algorithms has
to be written by yourself.
