◆ AppendValue2()

BOOL BUI::CChartSeriesLinePoints::AppendValue2	(	double	v2,
		BOOL	is_mark = FALSE,
		BOOL	check_range = TRUE,
		BOOL *	is_full_swap = NULL )

添加数据点的v2值

参数

v2	数据
is_mark	是否标记数据
check_range	自动计算v2范围
is_full_swap	输出参数。TRUE代表已到达最大显示容量,触发前后缓冲区交换。

返回: BOOL: 若返回TRUE，则表示需要刷新。若为FALSE，则不需要刷新

◆ AppendValue2ByArray()

BOOL BUI::CChartSeriesLinePoints::AppendValue2ByArray	(	double *	v2,
		int	count,
		BOOL	check_range = TRUE )

添加多个数据点的v2值

参数

v2	数据起点指针
count	数据长度
check_range	自动计算v2范围

返回: BOOL: 若返回TRUE，则表示需要刷新。若为FALSE，则不需要刷新向指定缓冲数组中添加数据。

void BUI::CChartSeriesLinePoints::AppendValuePair	(	double	v1,
		double	v2,
		BOOL	check_range = TRUE )

添加数据点(v1,v2)。注意:AppendValuePair不可以和（AppendValue2，AppendValue2ByArray）同时使用。

◆ ClearPoints()

void BUI::CChartSeriesLinePoints::ClearPoints ( BOOL clear_v1 = TRUE )
