Greetings from Syncfusion. We have checked the video and not figured the reported issue in the attached video, it seems like delay in render the chart.
You have reported that after multiple time of zoom performed chart is updated, but in the video, it not seems like performing zoom.
We suspect that you are using category Axis in Chart. When you have large amount of data in category axis, it will affect the performance since it is always rendered based on the index value. So, we suggest follow the chart performance improvement blog.
Still you are facing performance related issue, please share your Mock-up project or code snippet with data points used in your application with replication steps. This will be helpful for us to investigate further and provide you a better solution at the earliest.
