如何访问核心图中单个条的CALayer？ [英] How to access CALayer of individual bar in core-plot?

问题描述

我试图在图表中的每个条上执行动画，但是我不太确定如何访问每个条的calayer。

I am trying to perform an animation on each bar in the chart, however I am not quite sure how to access the calayer of each individual bar.

推荐答案

没有一个。所有条形图都绘制在一层中。如果需要分别为它们设置动画，请为每个条制作一个单独的 CPTBarPlot （ CALayer 的子类）。

There isn't one. All of the bars are drawn in one layer. If you need to animate them individually, make a separate CPTBarPlot (a subclass of CALayer) for each bar.
