HI, I am creating a custom line chart for charting stock tick prices. I am using the code from Olav Lerflaten posted on this site. http://aspnet.4guysfromrolla.com/demos/printPage.aspx?path=/articles/080603-1.aspx<BR><BR>My problem is this. The chart is only plotting 1 value point per Category point. I am getting sql data comprised of 2 fields DT(DateTime) and Spot(price). When running the query I am converting the Datetime field into the Hour in which the tick occured. So I end up with 60 value points PER category point. The data is then put into arrays then used in the SetData Method.<BR><BR>If I don&#039;t convert the DT field then I get all my points but end up with an ugly axis labels. I need to have all data points and the labels on the category axis to be the hour of the day. 0,1,2,3 Etc.<BR><BR>Suggestions??<BR><BR>Thanks<BR>
