@efkan,
To zoom into a certain region, there should be a minimum of 3-4 dataPoints in a dataSeries – behavior is designed such that zooming is limited upto a certain region, so the user doesn’t end up zooming into a blank-region (region with no dataPoints). Due to this restriction, it’s not possible to zoom into the region with just 1 dataPoint in a dataSeries.
