データに基づいて列の色を動的に設定できますが、凡例の色を変更する方法がわかりません。jsfiddle に注目してください。最新のバーは緑色ですが、凡例は青色です。列の色を変更すると凡例の色も変わる方法はありますか?
列の色に使用するコードは次のとおりです。
jsfiddle: http://jsfiddle.net/VCjZx/2/
function makeRun() {
var divId = "container";
var current = new Array(99.95,99.96,99.97,99.98);
var goal = new Array(99.965, 99.965,99.965,99.965);
var quarters = new Array("Q1", "Q2", "Q3", "Q4");
var width = 495; var SizeOfFont = '14px'; var currentName = 'Quarterly %';
preprocessData = function (data, goal) {
var nData = [];
var colorGood = '#348017'; var colorBad = '#E42217'; var colorUse;
for (var i = 0; i < data.length; i++) {
if (data[i] >= goal[i]) { colorUse = colorGood; }
else { colorUse = colorBad; }
nData.push({
y: data[i],
x: i,
color: colorUse
});
}
return nData;
};
