Marker points disappear after zoom

Hello all have a good day! I have a problem with time series, zoomable chart. I need to insert many data about 5000 but the problem is that when I zoom in then the markers disappear. Also I don't know why the label appear on chart as you can see on picture in url.

Hello tZoko,

Welcome to our forum and thanks for contacting us with your question!

Large data number shouldn't be the cause of the issue. It is also hard to tell why that text appears on your chart. Unfortunately these details aren't sufficient to tell what is wrong. Please try to reproduce your issue in a form of a live demo. You can start here: https://jsfiddle.net/BlackLabel/dtyj7hxa/

Hello,
Thanks for your reply. It seems to work fine here https://jsfiddle.net/vh8zsaj5/. I have noticed that if the values in table are preloaded it works fine but if I get the table from my database and load it in a table zoom doesn't work.

Re: Marker points disappear after zoom

Hi tZoko,

Once again, without issue reproduction it is really hard to tell what might be the cause. If you say that preloaded values works fine, then I would bet that your initial problems could be related to asynchronous behaviour of getting data from db. You've also mentioned that the zoom doesn't work as intended when you get data from db. Solution in this case would be most likely to handle data fetching properly and make sure that required data is ready to use with a chart.

Best regrads!
