我想绘制使用画布覆盖蜡烛图上的水平线，我得到一个错误：对象不支持属性或方法'series_u2p'错误？jqplot - 画布覆盖不工作蜡烛棒图
任何想法可能是什么原因？

嗨，本例是完全functionnal并可以帮助你：http://jsfiddle.net/WdLnm/135/ – sdespont 2012-08-10 05:40:32
感谢您的答复，由于某种原因，它不是与蜡烛棒图工作，它得到这个错误 TypeError：plot.axes [obj.options .yaxis] .series_u2p不是函数 [Break On This Error] \t y = plot.axes [obj.options.yaxis] .series_u2p（obj.options.y）， – user1589242 2012-08-10 14:21:06
