Thanks for the feedback. Indeed, this is a limitation in the zoom/scroll functionality in RadChart. I will forward your report to our developers, so they will consider the existing possibilities for improving the behavior in this scenario. Still, I am afraid no certain time frame is available at the moment.
Please, accept our apologies for the inconvenience.
