Is there any possible way to Zoom in Zoom out the Charts, We tried with Data navigation scroll and zoom feature ,but it has a limitation that x-axis value must be of date type. How to achieve the same for other data types?
For the time being I can suggest that you attach to the drag, dragEnd and zoom events of the chart and manually filter the data source when these events occur. See an example in this forum post - http://www.telerik.com/forums/yaxis-not-scaling-properly
