Description
The OnGetYValue event occurs when the Surface Series needs to recreate the grid of values. Calling the ReCreateValues method forces Surface Series to be created again. You should return the corresponding Y value for a given X and Z values. Usually you will place a formula or algorithm that calculates its value based on X and Z parameters.
