我正在定制OFC2的布局，以便它可以适合我的软件。但是，我对该图表的一个关注是，虽然它可以在同一个窗格中生成多个折线图，但我还没有找到图表的图例。 （例如，描述中空紫色线表示数据A，黄色线表示数据B等的小描述）当我使用折线图时，有没有办法实际执行此操作？我已经看到它在饼图中可用，但它不适用于图表BTW。
评论，建议甚至样本JSON都将受到高度赞赏。
答案 0 :(得分：0)
你必须在“元素”中使用“text”元素
例如："text": "Google Inc. (NASDAQ:GOOG)"
如下所示：http://demo.webasp.com.au/ofc-explorer-k.html
例如JSON：
{
"title": {
"text": "Google vs Apple Stock"
},
"elements": [
{
"type": "line",
"text": "Google Inc. (NASDAQ:GOOG)",
"font-size": 12,
