iOS Scatter核心情节有差距 [英] iOS Scatter core plot with a gap

问题描述

如何使用核心图绘制带有间隙的散点图？我正在使用核心情节库。一切都工作正常，但现在我想做一个散点图，在数据线的开头或中间有间隙？有人帮我吗？

How does one draw a scatter plot with a gap using core plot? I was using the core plot library. Everything is working fine but now I want to do a scatter plot with a gap at the beginning or in the middle of the dataline? Someone help me please?

推荐答案

让数据源返回 nil 或 [NSNull null] 。例如，如果绘图有五个数据点，并且您为索引2处的x或y字段返回 nil ，则绘图将绘制由连接的索引0和1处的点。一条线和指数3和4由一条线相连，中间有一个间隙。

Have the datasource return nil or [NSNull null]. For example, if the plot has five data points and you return nil for the x or y field at index 2, the plot will draw the points at indices 0 and 1 connected by a line and indices 3 and 4 connected by a line with a gap in between.
