Hi Justin,
Thank you for posting your query to us.
I am afriad that I was not able to reproduce the issue "Chart crashes when adding more number of points in a series" in the latest version 5.1.0.51 which you have mentioned in the previous update.
Please refer the attached sample.
http://websamples.syncfusion.com/samples/Chart.Windows/F36335/main.htmThe above sample which illustrates how to add a more number of points[10,000] in a series.
Please have a look at the above sample and if still the issue exists could you please try reproducing it in the above sample or send us the reproducing steps so that we could sort out the cause of the issue and provide you a solution?
Could you please let me know what version of Essential Studio you are using?
Regards,
Rashidha.
