Can you provide more information on how you're setting up the labels and plot 
space? I was unable to reproduce the problem.

I made some changes to my copy of CPTestApp to give the bar plots labels and 
allow them to scroll. Everything worked as expected.

Hi,
Firstly i set plotspace
plotSpace=(CPXYPlotSpace *)self.graph.defaultPlotSpace;
    plotSpace.xRange=[CPPlotRange
plotRangeWithLocation:CPDecimalFromFloat(X_MIN)
length:CPDecimalFromFloat(X_MAX+0.50-expand_graph_value)];
    plotSpace.yRange=[CPPlotRange
plotRangeWithLocation:CPDecimalFromFloat(Y_MIN)
length:CPDecimalFromFloat(f2+2.0)];
    plotSpace.allowsUserInteraction = YES;
    plotSpace.delegate=self;
    plotSpace.identifier=@"barplot";

After that i added
barPlot1.barLabelTextStyle=whiteText;
  barPlot1.barLabelOffset=1.0;

But when i am scrolling graph its not working.

You only have the one plot space, right? Are all of your plots (if there are 
more than one) tied to the same plot space?

What is your plot space delegate doing? Can you post your delegate methods?
