JFreeChart 9.20的文档 需要用JAVA在网页上做统计图的东东

 The segment range is identified by a domainValue that begins a valid segment and ends
 with a domainValue that ends a valid segment. Therefore the range will contain all
 segments whose segmentStart <= domainValue and segmentEnd <= toDomainValue.

<DD>Adds a segment as an exception. An exception segment is defined as a segment
 to exclude from what would otherwise be considered a valid segment of the timeline.
 An exception segment can not be contained inside an already excluded segment.
 If so, no action will occur (the proposed exception segment will be discarded).
 <p>
 The segment is identified by a Date into any part of the segment.

 to exclude from what would otherwise be considered a valid segment of the timeline.
 An exception segment can not be contained inside an already excluded segment.
 If so, no action will occur (the proposed exception segment will be discarded).

<A NAME="addBaseTimelineException(long)"><!-- --></A><H3>
addBaseTimelineException</H3>
<PRE>
public void <B>addBaseTimelineException</B>(long&nbsp;domainValue)</PRE>
<DL>
<DD>Adds a segment relative to the baseTimeline as an exception. Because a base segment is
 normally larger than our segments, this may add one or more segment ranges to the
 exception list.
 <p>
 An exception segment is defined as a segment
 to exclude from what would otherwise be considered a valid segment of the timeline.
 An exception segment can not be contained inside an already excluded segment.
 If so, no action will occur (the proposed exception segment will be discarded).
 <p>
 The segment is identified by a domainValue into any part of the baseTimeline segment.

addBaseTimelineException</H3>
<PRE>
public void <B>addBaseTimelineException</B>(java.util.Date&nbsp;date)</PRE>
<DL>
<DD>Adds a segment relative to the baseTimeline as an exception. An exception segment is 
 defined as a segment to exclude from what would otherwise be considered a valid segment 
 of the timeline.
 An exception segment can not be contained inside an already excluded segment.
 If so, no action will occure (the proposed exception segment will be discarted).
 <p>
 The segment is identified by a domainValue into any part of the segment.
 Therefore the segmentStart <= domainValue <= segmentEnd.
