• • I have a bar chart that shows a count of items, by category. When the counts are small, the axis tickmark values show non-integer values - for example when the axis scale is 0 to 5, there is a major tickmark for every 0.5 units. Is there a way to force the axis scale to show integer values only?

Hello Christer,

Please use the following code snippet to accomplish this task:

            (chartControl.Diagram as XYDiagram).AxisY.GridSpacingAuto = false;
            (chartControl.Diagram as XYDiagram).AxisY.GridSpacing = 1;

I've attached a sample project demonstrating this in action. Please let me know if you experience any further difficulty.

Thanks,
Alessandro.

  Thanks - that did the trick (combined with a check for the axis range).

  Is there any way to have gridspacingauto = true, but have the grid NOT show decimals when y-axes values are low?
  
  I‍ like the function of the auto, but when the values are less than 5, for instance, the y-axes starts showing decimals.  This confuses my users who expect to see whole units (integers) only.
