  28  <H3><A NAME="10_9_1">10.9.1 Adding caption to bars</A></H3>
  29  <P> Caption for bars are placed at the far right side of the bars. They
  30   can for example be used to indicate the resources assigned to a task,
  31   the duration of the task or the progress of the activity.</P>
  32  <P> Caption text for a bar is specified either when creating a bar or
  33   later by accessing the 'caption' property of bars. So the two lines<DIV class="phpscript">
  34  <CODE><FONT color="#000000"> <FONT color="#0000BB">&nbsp;$activity&nbsp;</FONT><FONT
  35  color="#007700">=&nbsp;new&nbsp;</FONT><FONT color="#0000BB">GanttBar</FONT><FONT color="#007700">

  46  );</FONT><FONT color="#0000BB"></FONT></FONT></CODE></DIV></P>
  47  <P> are both ways of specifying the caption &quot;[BS,ER]&quot; for the activity.
  48   Since activity is a standard JpGraph text object you can easily modify
  49   font, color and size with calls to SetFont() and SetColor(), (e.g.<DIV class="phpscript">
  50  <CODE><FONT color="#000000"> <FONT color="#0000BB">&nbsp;$activity</FONT><FONT
  51  color="#007700">-&gt;</FONT><FONT color="#0000BB">caption</FONT><FONT color="#007700">
