Hi Gian,
Greetings from Syncfusion.
We would like to let you know that we have already considered this “Support for 3D chart with z values “ as feature and we have already logged a feature request on this, and it can be tracked through our feedback portal below.
Please cast your vote to make it count. We will prioritize the features every release based on the demands and we do not have an immediate plan to implement this feature since we committed with already planned work. So, this feature will be available in any of our upcoming releases.
If you have any more specifications/suggestions to the feature request, you can add it as a comment in the portal.
Please let us know if you need any further assistance on this.
Regards,
Suyamburaja J.
