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.

You can get visible range of X-Axis using code like this: space.graph.axisSet.xAxis.visibleAxisRange
