int BCGPChartSmartLabelParams::m_nMaxAllowedDistancePercent

Controls distance of data labels from data markers.

The distance is specified in percents in interval [100, 1000]. The distance calculation is based on the default distance from data marker, which is defined by CBCGPChartSeries::SetDataLabelDistanceFromMarker. The default distance is 15 pixels. The default interval is 300 percents, so the distance will be adjusted from 15 pixels to 45 pixels.
