Unable to remove negative axis in Scatter Plot using Core-plot2.0

I have set the plotspace with X and Y Ranges but still I get to see the negative axes. Thoughts anyone?

 // Setup scatter plot space
    CPTXYPlotSpace *plotSpace = (CPTXYPlotSpace *)graph.defaultPlotSpace;
    plotSpace.allowsUserInteraction = YES;
    plotSpace.delegate              = self;

    plotSpace.xRange = [CPTPlotRange plotRangeWithLocation:[NSNumber numberWithFloat:0.0] length:[NSNumber numberWithInt:2]];
    plotSpace.yRange = [CPTPlotRange plotRangeWithLocation:[NSNumber numberWithFloat:0.0] length:[NSNumber numberWithInt:2]];

Please check the image to see how it looks enter image description here

Solution

  • I was able to achieve the solution just by setting the visible ranges for both the axis.

    x.visibleRange   = [CPTPlotRange plotRangeWithLocation:xMin length:[NSNumber numberWithDouble:([xMax doubleValue] - [xMin doubleValue])]];
y.visibleRange   = [CPTPlotRange plotRangeWithLocation:yMin length:[NSNumber numberWithDouble:([yMax doubleValue] - [yMin doubleValue])]];
