Getting custom study subgraph lines to display when originating offscreen

I'm creating a custom study very similar to the Zig Zag study that exists in Sierra Chart. I have a subgraph holding the values for the start and end nodes of the zig zag lines. However, my problem is the lines do not draw if either the start or end node is scrolled to a position off-screen. I would like for the lines to draw if either the start or end node is visible on the chart. The native Zig Zag study in Sierra Chart works correctly and is how I'd like the lines to be drawn.

Thanks

You need to be sure that all elements of a study Subgraph Data array are set.

Thanks for the reply. This does solve the problem. I solved for the equation of a line for each index of the zig zag. If there is an easier way please let me know. Otherwise, you need to update each subgraph data element every time the zig zag is updated.
