//to use this function you need to link to it with <script language="javascript">createPrintButton()</script>
//and include  custom_print('1,'1') in the body onload.  If the graph doesn't print, increase the two numbers in the function. default 1 for ie and 1 for ns.
//I found on some machines nn4.0-4.08 would not show the graph at all.  This however I believe was due to them not having enough java support.  I have thus built this to work for this browser as I know when set up correctly it can print the graph.
