円グラフの凡例が小さすぎます。テキスト サイズを大きくするにはどうすればよいですか。コードは次のとおりです。
<?xml version="1.0" encoding="UTF-8"?>
<html lang="en">
<head>
<meta charset="utf-8">
<script src="raphael-min.js"></script>
<script src="g.raphael-min.js"></script>
<script src="g.pie-min.js"></script>
<script>
window.onload = function () {
var r = Raphael("holder");
pie = r.piechart(320, 240, 100, [10,20,0,0],
{
legend: ["%% Unknown","%% Recognisable","%% Familiar","%% Known"],
colors: ["#FF0000","#FFB2B2","#CCFFCC","#00E600"],
legendpos: "west"
});
};
