I am using a datetime field as the x-axis coordinate. When viewing the x-axis in the designer, I am getting the dates formatted in the mm/dd/yyyy format. When I run the chart, however, I am getting 0 thru 100 as the x-axis labels. Changing the XAxis.LabelsFormat.CustomFormat property to mm/dd/yyyy displays correctly in the designer, but when run in production, displays the text "mm/dd/yyyy" as the x-axis label. Any idea's? Scott.
