<H3><A NAME="9_7_1">9.7.1 Specifying vertical position</A></H3>
<P> As described above vertical positions are specified as a numeric
 value [0..n] where 'n' is an arbitrary constant. (For practical
 purposes n is most likely &lt; 100)</P>
<P> Using our previous example we will illustrate this parameter by
 changing the position of our 'Project' activity to position 7. Therefor
 we change the call to GanttBar() to<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">

);</FONT><FONT color="#0000BB"></FONT></FONT></CODE></DIV></P>
<P> and we then get the chart as shown below in Figure 150.</P>
<P><DIV class="example">
<BR> <A href="exframes/frame_ganttex03.html" target="blank"><IMG border="0"
HEIGHT="280"       src="img/img/img/img/img/img/ganttex03.png" WIDTH="486"></A>
<BR><B>Figure 150:</B> Changing the vertical position to 7 <A href="exframes/frame_ganttex03.html"
target="blank">[src]</A>&nbsp;
<P></P>
</DIV></P>
<P> Note that the height of each position (vertical position) will
 depend on the actual height of the bar.</P>
