Help With Crystal Report Chart

Hello,
I am having a problem with a chart in a crystal report and was wondering if anyone could help as I am not too familiar with designing reports and charts. The chart is a date axis type chart and the problem is, if I have multiple items in the chart that have the same value, the connector lines are on top of one another. Is there anyway to prevent this? Possibly set the connector lines to have different line styles by default so even if they are on top of one another they can be seen?
Thanks
