void CBCGPChartBarSeries::SetColumnDistancePercent ( int  nPercent = 150)

Sets column/bar distance.

This value measures, in percents from column or bar size, the distance between left/right column or bar in a group (a "group" means a couple of data points of distinct series having the same X coordinate and therefore placed on the same major unit) and bounds of their major unit.

This setting has the same effect for all series displayed on the same axis, e.g. it's enough to call this method for one series. For example:

Copy
pSeries1->SetColumnDistancePercent(50);
pSeries2->SetColumnDistancePercent(25);

"Series1" and "Series2" will be displayed with distance 25%.

Parameters
nPercentSpecifies the distance in percents from a column/bar size. Should be in range [0, 100].
