Changing the style of one plot in a multiple plot graph

[X.]

I am exploring the toolkit capabilities and I am struggling to understand the way mutiple plots are handled internally.

For instance, the way a multiplot graph is created is as follows (modified from the Line Plot.vi):

This will give this as a result:

So, even though a single New Plot ID is created, two plots are drawn, each one with its own style.

That makes a "Plot ID" something more like a "Graph ID" than a single plot identification.

Now, suppose I want to change the style of plot 2 only.

So far, it looks like I have to redraw plot 1 and 2 with their individual styles just as when I created the first version of the graph.

Am I missing something?
