Add annotation in 3d chart

Hello, everyone.

I want to add annotations for analyzing 3d charts.
In order to do that, it is necessary to be able to make several marks on the X-axis, Y-axis, and Z-axis, and I would like to know the best practices.

please check the attached picture. It is similar with cursor but it’s fixed.
I found Custom Geometry documents.
https://www.scichart.com/documentation/win/current/webframe.html#Adding%20Cubes%20and%20Custom%20Geometry%20to%20the%20Chart.html
but I am not sure this is for the best.

Thanks,
Kim, JinSeok.
