Setting plotSpace.globalYRange=plotSpace.yRange causes y axis to draw wrongly.

Still new to objective-c, so im not sure its actually a bug. Using core plot 
2.2.

What steps will reproduce the problem?
The graph looks correct. I change some plot data and reload using the 
reloadData call, then i rescale y-axis using: 

Works:
    plotSpace.yRange = [CPPlotRange plotRangeWithLocation:CPDecimalFromFloat(min*(1-coeff))
                                                   length:CPDecimalFromFloat(max*(1+coeff)-min*(1-coeff))];

    plotSpace.globalYRange = [CPPlotRange plotRangeWithLocation:CPDecimalFromFloat(min*(1-coeff))
                                                         length:CPDecimalFromFloat(max*(1+coeff)-min*(1-coeff))];

Fails:
    plotSpace.yRange = [CPPlotRange plotRangeWithLocation:CPDecimalFromFloat(min*(1-coeff))
                                                   length:CPDecimalFromFloat(max*(1+coeff)-min*(1-coeff))];

    plotSpace.globalYRange = plotSpace.yRange;

What is the expected output? What do you see instead?
Expected: Correct rescale of y axis, but the result is axises / graph is way 
out of the plot area.

Using core plot 0.2.2.

Are you resetting the ranges on an existing graph? If so, remember that the 
previous globalYRange will constrain the new setting. Try setting the 
globalYRange to nil before setting a new yRange.

Thanks for the help. Setting them to nil first, fixed my problems and some 
other issues i was having reloading data.
