Janky performance when chart has many points

Hi, I have a chart that shows blood concentrations of a drug over time, and this has to be quite specific and the timeline is about 24 hours. When showing the concentration every 5 seconds though, this leads to about 20.000 points and this kills performance (i.e. when panning or zooming the performance is very janky and slow), is there anything that I can do to help? I am using a line chart, because spline chart was even slower.

Thanks,

Luca

Hi Luca, 

Thanks for using the Syncfusion Flutter Chart widget. We have analyzed the reported scenario, unfortunately, the scenario is not replicated. The sample used for testing can be found below. 
We would like to let you know that we have included some performance improvements in our vol 1 beta release (v18.1.36). Since you are using the line series, you can also FastLineSeries, this will have better performance in comparison with line series. If you face still any concerns, kindly try to reproduce the reported issue with the above sample or provide your sample with replication steps. This will be helpful in providing the solution earlier.  

Thanks, 
Dharani.
