First of all, could you make your graph-generator produce two
images, one for the graph and one for the legend ? I suppose yes.
Then I also suppose you know the dimension of legend image. It
doesn't matter if you don't, you would just need to open a new window
large
enough.
Then somewhere in the page which displays the graph, you need
something like the following code :
<body .....>
<img src=3D"your_graph.gif">
<script language=3D"JavaScript">
<!--
var lgdwin =3D window.open("your_legend.gif", "lgdwin",
"width=3D100,height=3D100,status=3D0");
// -->
</script>
......
</body>
