  28  <H3><A NAME="10_9_2">10.9.2 Adding progress indicators to bars</A></H3>
  29  <P> To indicate the progress of a specific activity it is also possible
  30   to add a progress indicator to each bar. This progress indicator
  31   consists of a smaller bar within the bar. By default this progress bar
  32   is black and 70% of the height of the bar. These parameter can (of
  33   course) all be changed.</P>
  34  <P> The properties for the progress indicator are accessed through the
  35   'progress' property and it's methods.</P>
  36  <P> To set the progress for a specific activity you only specify the
  37   percent as a fraction. As in<DIV class="phpscript"><CODE><FONT color="#000000">
  38   <FONT color="#0000BB">&nbsp;$activity</FONT><FONT color="#007700">-&gt;</FONT><FONT
  39  color="#0000BB">progress</FONT><FONT color="#007700">-&gt;</FONT><FONT color="#0000BB">
  40  Set</FONT><FONT color="#007700">(</FONT><FONT color="#0000BB">0.4</FONT><FONT
  41  color="#007700">)</FONT><FONT color="#0000BB"></FONT></FONT></CODE></DIV>
  42  </P>
  43  <P> In Figure 158 the previous example is modified to indicate the
  44   progress of each activity by the default progress indicator. A solid
  45   bar. To make it clearer we have also modified the caption to reflect
  46   the displayed progress. (At the same time we also modified the scale
  47   headers just to illustrate some more formatting options).<DIV class="example">
  48  <BR> <A href="exframes/frame_ganttex14.html" target="blank"><IMG border="0"
  49  HEIGHT="191"  src="img/ganttex14.png" WIDTH="409"></A>

  52  <P></P>
  53  </DIV></P>
  54  <P> To specify a different format for the progress you use the
  55   SetPattern() method as in<DIV class="phpscript"><CODE><FONT color="#000000">
  56   <FONT color="#0000BB">&nbsp;$activity</FONT><FONT color="#007700">-&gt;</FONT><FONT

  63   available methods.<DIV class="example">
