<H3><A NAME="8_1_1">8.1.1 Simple radar plots</A></H3>
<P> Let's start by creating a very simple radar plot based on 5 data
 points using mostly default values.</P>
<P> As the first thing you must remember to include the extension module
 that contains the radar plot. &quot;jpgraph_radar.php&quot;.</P>
<P> A very simple radar plot is created by the code<DIV class="phpscript">

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