setting X axis labels to display only integers

[Ben Tsai]

Hello,

I am currently using the chart control bound to a dataset. I have enabled X scrolling/zooming. Although my series contains only integers, sometimes when I zoom, the X axis labels are automatically set to non-integer values.

This makes sense, because the ValueType of the axis is Double, but is there a way to force the behavior to display only integer values?

I tried changing RoundingPlaces to 0, but this results in a divide-by-zero exception.

Thanks.

Hi BenT,

Thank you for choosing Syncfusion products.

It is possible to set the integer values for an Axis while Zooming using RoundingPlaces and Format property of an Axis. The following code illustrate this :


this.chartControl1.PrimaryYAxis.RoundingPlaces=0;
this.chartControl1.PrimaryXAxis.Format="###";

But I was not able to reproduce the divide-by-zero exception when setting RoundingPlaces to zero.

Please try the attached sample which helps you to display the Axis values in integers after zooming.

Kindly let me know if this helps.

Thank you for your reply, Jaya.

Changing the PrimaryXAxis.Format property appears to achieve the behavior I wanted.

I wasn''t able to properly run your example - I receive a "Object reference not set to an instance of an object." when attempting to zoom. But my issue has been resolved.

Best regards.

Hi BenT,

Glad to hear that your issue is resolved.

To avoid the exception you faced,you need to change the connection string according to the location where you stored the database file in your system.
