BOOL CBCGPChartAdvancedFormula::m_bUseLongData

Defines how data points are added to the output series.

If this member is TRUE data points are added in batch. It improves performance and memory consumption, but disables customization of individual data points (the output series will work in optimized long data mode).

Set this member to FALSE if you have few data points and need to customize their appearance individually.

The default value is TRUE.
