On my UltraChart when I pass in a Decimal, it is incorrectly rendering the labels up the left side, for example if I pass in one column value as 4.00, the left hand columns will display the top max value of "400%"... not 4%.
I am currently using this as a data value:
chart.Axis.Y.Labels.ItemFormatString =
"<DATA_VALUE:##.##%>";
Try taking the % character outside the angle brackets:chart.Axis.Y.Labels.ItemFormatString = "<DATA_VALUE:##.##>%";
In this case the % will be treated as a character.
