Re: how to highlight an entire column in a scatter graph

[Eric]

Use a "background limit band" on the x-axis. See Axis Demo in the Plot Gallery example app for sample code.

thanks in advance!

great, that worked, thanks! I'm posting the code I've added for future readers:

CPTFill *bandFill = [CPTFill fillWithColor:[[CPTColor whiteColor] colorWithAlphaComponent:0.7]];

        [x addBackgroundLimitBand:[CPTLimitBand limitBandWithRange:[CPTPlotRange plotRangeWithLocation:CPTDecimalFromDouble(month-0.5) length:CPTDecimalFromDouble(1.0)] fill:bandFill]];

Just one more quick question. I've looked into the Axis Demo example, but I can't figure out why in my chart the limit band goes under the x-axis. I think it's because of the minor grid, since it finishes when the dash line finishes. But how can I change those values to stop at 0?
