Feature request: change z-order of type1000 layers after creating them

[btgoodwin]

Current behavior: the creation of the layer (e.g., overlay_pipe) establishes the z-order of the layer when drawing each layer.

What we would like to do is re-order layers in the event a signal on layer 1 needs to temporarily be displayed ahead of layer 0 (0 and 1 being indices into the layer list).

@btgoodwin how does this API look:

sigplot/test/tests.js

Line 4950 in 17b1a24

interactiveTest('zOrder layer option', 'Is the red triangle over-top the green triangle with no blue showing?', function() {

If this looks good to you I will merge this onto the mainline.

Thanks, I like that. @tplumley, FYI as we rebase against the new 2.0 master.

I haven't gone through the code, but what would happen if I set a z-order of 3 and then pushed several layers (such that 0, 1, 2, ...)? Would that next layer end up at zOrder 4, skipping 3 since that one was manually assigned?

Currently you would end up with: Layer 1 - zOrder 3 Layer 2 - zOrder 1 Layer 3 - zOrder 2 Layer 4 - zOrder 3 But your inquiry brings up a good point. I'm going to change that so that new layers are always added on top of all existing layers (i.e. new layers zOrder = max(zOrder)+1) unless a zOrder was explicitly provided. I'll update that tonight and push new changes to this branch. ~Michael
