In Core-Plot I want to plot only the visible area of the plot. For this I need the visible range of the plot after Zoom-In and Zoom-Out.
Any Idea how to get visible range of X-Axis?
You can use a plot space delegate to find out when the plot ranges change. Each delegate method receives a reference to the plot space as one of its parameters. You can read the xRange
and yRange
to find out what the new ranges are.
您可以使用以下代码获取X轴的可见范围: space.graph.axisSet.xAxis.visibleAxisRange
