Hi Joa,
By "add mark", I assume you are referring to mark lines added by Axis.addMark.
Do you mean after you have created and displayed the surface chart, you would like to add
a mark line to the chart? To do so, simply recreate the chart with a mark line.
You may use the "Interactive Financial Chart" sample code as a reference. In this sample
code, users can add or remove many types of indicator lines on the chart. Although this
sample code is for a financial chart, its techniques are applicable to any chart type. Basically, there is only one subroutine for drawing the chart, and it can draw all the
indicators based on certain parameters. When the user wants to add or remove things, the
parameters changed, and the subroutine can be called to redraw the chart from the update
parameters.
Hope this can help.
