Hopefully this is a simple one!

I have created a line chart with an x axis of -60 thru 300

This works OK. For presentation purposes (dont ask !) it is requested that the data is centered on the chart, so the simpliest route i though of was increasing the range to -90 to 330. This created the required result, however I dont want to see the -90 and 330 on the x axis.. Is there anyway around this?

(there may be more questions to follow!)

Thanks
