CBCGPChartLongSeries

Detailed Description

The CBCGPChartLongSeries class implements a line series, which is optimized to handle a large amount of data (hundreds thousands of data points).

Because of optimization the series has some limitations: it can't display data markers and data labels.

The long data series ignores X values, all data points are displayed according to their index.

If a lot of data is displayed on a single pixel, it produces some "noise" on the diagram and slows down redrawing. Call SetFilterSimilarXValues() to reduce the "noise". The series will perform additional optimization and display average Y values calculated among all values falling on the same pixel (it may be not suitable for some cases, because average hides the real picture).
