formatting data axis for a line chart within crystal reports

Hello,

I have a web application that produces reports on data retrived from an inSQL database
I need to plot the data in a line chart, the data is logged every 60 seconds.
The maxium time scale for the report is 6 hours.
I need to display all 360 (6 hours of data) data points, but I don't want to display all the labels.

I need to define the numbers of labels to about 6, is this possible?

Thanks,
Tom Ashley
