Hi Halber,
Greetings from Syncfusion.
We have ensured your reported scenario with attached
screenshot. Stock chart multiple series is rendered properly without any
exception. We have attached the tested sample and screenshot for your
reference.
Sample : https://www.syncfusion.com/downloads/support/directtrac/general/ze/MulStckChart-951427774.zip
We have also checked the loading time in JavaScript, chart
is rendered within 200 to 300 milliseconds. We have noted this difference in
sample itself. If you are still facing problem, please try to replicate an
issue in above sample or share us issue reproduced sample to validate this case
further from our end.
Kindly revert us if you have any concerns.
Regards,
Durga Gopalakrishnan.
