下面是我的路线图，其中我使用2线，以显示不同的值，线图不打表上正确的价值，并具有流畅的线条
一号线是蓝色的，而另一个是红色的。
我希望该行有尖锐的点。而且我希望线条坐在正确的位置上，我拥有gievn。例如，如果'28 dec'是值'4'并且'29 dec'是值'2'并且'30 dec'是值'5'，那么现在这些值并不是完全按照例如'Dec 25'该值为3，但在图表上线路将在3以下，看起来像2.5。这是因为线条是平滑的线条而不是尖锐的线条？
我想看看这条线上下锋利而不光滑。如果这是有道理的。我希望这是有道理的，因为我对
的JS拨弄我创建挣扎大时间为：https://jsfiddle.net/dave1231/cexLbfnk/2/
，如果有人能告诉我如何我将不胜感激了很多。
谢谢你提前！
