<H3><A NAME="9_9_1">9.9.1 Adding caption to bars</A></H3>
<P> Caption for bars are placed at the far right side of the bars. They
 can for example be used to indicate the resources assigned to a task,
 the duration of the task or the progress of the activity.</P>
<P> Caption text for a bar is specified either when creating a bar or
 later by accessing the 'caption' property of bars. So the two lines<DIV class="phpscript">
<CODE><FONT color="#000000"> <FONT color="#0000BB">&nbsp;$activity&nbsp;</FONT><FONT
color="#007700">=&nbsp;new&nbsp;</FONT><FONT color="#0000BB">GanttBar</FONT><FONT color="#007700">
(</FONT><FONT color="#0000BB">0</FONT><FONT color="#007700">,</FONT><FONT
color="#DD0000">&quot;Activity&nbsp;1&quot;</FONT><FONT color="#007700">,</FONT><FONT color="#DD0000">
&quot;2001-11-21&quot;</FONT><FONT color="#007700">,</FONT><FONT color="#DD0000">
&quot;2001-12-20&quot;</FONT><FONT color="#007700">,</FONT><FONT color="#DD0000">
&quot;[BS,ER]&quot;</FONT><FONT color="#007700">)</FONT><FONT color="#0000BB"></FONT>
</FONT></CODE></DIV></P>
<P> and<DIV class="phpscript"><CODE><FONT color="#000000"> <FONT color="#0000BB">
&nbsp;$activity</FONT><FONT color="#007700">-&gt;</FONT><FONT color="#0000BB">
caption</FONT><FONT color="#007700">-&gt;</FONT><FONT color="#0000BB">Set</FONT><FONT
color="#007700">(</FONT><FONT color="#DD0000">&quot;[BS,ER]&quot;</FONT><FONT color="#007700">
);</FONT><FONT color="#0000BB"></FONT></FONT></CODE></DIV></P>
<P> are both ways of specifying the caption &quot;[BS,ER]&quot; for the activity.
 Since activity is a standard JpGraph text object you can easily modify
 font, color and size with calls to SetFont() and SetColor(), (e.g.<DIV class="phpscript">
<CODE><FONT color="#000000"> <FONT color="#0000BB">&nbsp;$activity</FONT><FONT
color="#007700">-&gt;</FONT><FONT color="#0000BB">caption</FONT><FONT color="#007700">
-&gt;</FONT><FONT color="#0000BB">SetFont</FONT><FONT color="#007700">(</FONT><FONT
color="#0000BB">FF_ARIAL</FONT><FONT color="#007700">,</FONT><FONT color="#0000BB">
FF_BOLD</FONT><FONT color="#007700">,</FONT><FONT color="#0000BB">9</FONT><FONT
color="#007700">);</FONT><FONT color="#0000BB"></FONT></FONT></CODE></DIV>

<P> The figure below illustrates the use of caption<DIV class="example">
<BR> <A href="exframes/frame_ganttex13.html" target="blank"><IMG border="0"
HEIGHT="186"       src="img/img/img/img/img/img/ganttex13.png" WIDTH="409"></A>
