  29  <P> Minute scale is the lowest resolution you can use. It is often
  30   convenient to use Minute scale with &quot;GanttScale::SetINtervall()&quot; since
  31   by default the increment will be 1 minute. The style of minute scale
  32   can be further adjusted by the use<I> style</I> parameters which can be
  33   one of</P>
  34  <OL>
  35  <LI> &quot;MINUTESTYLE_MM&quot;, This will display minutes as a two digit number
  36   with a leading zero if necessary</LI>
  37  <LI> &quot;MINUTESTYLE_CUSTOM&quot;, This will let you specify you own custom
  38   minute style by making a call to<I> HeaderProperty:: SetFormatString()</I>
  39  </LI>
  40  </OL>
  41  <P> Minute scale is enabled by adding the GANTT_HMIN in the
  42   GanttGraph::ShowHeaders() call. For example as in<DIV class="phpscript">
