Hy,

I want to zoom chart programmatically to a specific range of data, but I don't know what method to use.

Thank you,

Hello,

Thank you for your answer. 

1. I want to zoom and pan on DateTimeAxis, how can I use the ZoomByRange method?

2. More important, how can I zoom to fit on  numerical axis(the vertical one).

Thank you

You can achieve this requrimenet by passing start date and end date with DateTimeAxis in the ZoomByRange method of the ChartZoomPanBehavior. Please refer the following code snippet for more details.

 double startDate = new DateTime(2017, 10, 5).ToOADate();  

 double endDate = new DateTime(2017, 10, 7).ToOADate();  

  

 zoomPan.ZoomByRange(xAxis,startDate,endDate); // Specify the range to zoom  

  

  

ZoomByRange in NumericalAxis  

  

    

   zoomPan.ZoomByRange(yAxis, 0, 2); // Specify the range to zoom
