Other tips for passing -
You want it as warm as you can get it.  Keep it running the whole time, I'm
not suggesting this, but disconnecting the rad fan sender will get it really
warm temporarily at idle !

Multi-electrode spark plugs  -  I have read of people reducing emissions for
a smog test using those. 
I 'think' as you retard on timing NOx goes down, but too far and other
things go back up. 
Always consider 'lean misfire' too as a cause of failing  emissions results.

Not sure what to do about it, but I've heard that mentioned many times.

Your chart came out kinda funky on my screen, but it looks like
you're failing on NOx.  If that is the case, temporarily retard
your timing by 5-10 degrees.  That will lower the values enough
to get you through.

Could you please post emissions results when you do this?  I'd
like to know what the reduction actually is.  I have data for
another vehicle, but not for a WBX.
