  29  <P> Let's start by creating a very simple radar plot based on 5 data
  30   points using mostly default values.</P>
  31  <P> As the first thing you must remember to include the extension module
  32   that contains the radar plot. &quot;jpgraph_radar.php&quot;.</P>
  33  <P> A very simple radar plot is created by the code<DIV class="phpscript">

  74  <P> To change the size and position of the radar graph is similar to the
  75   pie plot and you do it by using the methods <A href="../ref/SpiderGraph.html#_SPIDERGRAPH_SETSIZE">
  76   SetSize()</A> and <A href="../ref/SpiderGraph.html#_SPIDERGRAPH_SETCENTER">
  77   SetCenter()</A></P>
  78  <P> If you want a filled radar plot you need to specify the fill color
  79   with the method <A href="../ref/SpiderPlot.html#_SPIDERPLOT_SETFILLCOLOR">
  80   SetFillColor()</A> The following example shows these methods in action<DIV
