推荐答案

还没有Legend类。你可以使用图像有时伪造它，但它不是在核心绘图。 检查drewmcco评论

图例尚未在Core Plot中实现。

Legends have not yet been implemented in Core Plot. You're more than welcome to contribute an implementation of them to the framework.

在此期间，您可以使用UILabels和彩色线条构造一个自定义UIView作为图表的图例，然后将其作为同级添加到图表（而不是子视图，或将不会正确呈现），并命令它显示在图表上方。
检查Brad Larson答案

In the meantime, you could construct a custom UIView with UILabels and colored lines to act as the legend for the graph, then add it as a sibling to the graph (not a subview, or it will not be rendered properly) and order it to show above the graph. Check Brad Larson Answer
