I have data like 0.00834 but chart is rounding it and showing it as 0.01.
But I want to see the data as is. Could you please help.
By default the format string allows at most 2 decimal places. To change that, set chart.Axis.Y.Labels.ItemFormatString property to "<DATA_VALUE>" instead of "<DATA_VALUE:00.##>". If you were talking about the value in the tooltip, then use chart.Tooltips.FormatString property.
