class TMtxFastLineSeries : public TCustomLineSeries;
A series for fast drawing of a line series.
The series uses PixelDownSample internally to speed up the drawing of the line series. This allows for the series to draw correctly also during zoom-in and pan operation. Only the color of the line can be customized and the step on the X axis must be fixed between consecutive elements (no nulls allowed either). The series is about 3x faster than TMtxFastLineSeries from TChart, when PixelDownSample is not even active yet.
Note
To benefit from the increased drawing speed, use the DrawValues function to add data to the series, to speed up also the value adding process.
