[Solved] Multi-line formula with arrows between

[dannio]

Hello! I would like to use the following:

Code: Select all

NK → MK                FRK[1] → FRK[2] 
        ↓                ↑  
	     PMP(a)          PMP         
	   ↓     ↓            ↑          
      PMP(b)   PMP(c) → PMP  

and put only a right brace alongside the bottom three lines with a label describing them which will say "PMP complex." I have no idea how to do this. I tried the lines of code earlier in this thread, and nothing worked. Please help!

The newline breaks the formula flow, iow you can't have interconnecting elements between lines when you use newline. Use stacking for that.

Code: Select all

alignl stack{ NK rightarrow MK FRK[1] rightarrow FRK[2]#
downarrow ~ uparrow #
left none 
stack {PMP(a) ~ PMP #
downarrow ~ downarrow ~ uparrow #
PMP(b) ~ PMP(c) rightarrow PMP  }
 right rbrace ~ "PMP complex"}

This may be rather difficult to do with OO Math--I assume you need to align some of the items and arrows to show specific vertical connections, no?

I'm not sure that Math is really helping you here very much; it would be a lot easier to treat it as a diagram and use OO Draw, where spacing and alignment are simpler.

If you need to do it Math, I think you'll need to set up a matrix to get all the parts aligned vertically.

I am a novice with doing things like this, so I appreciate everyone's help. Is there anywhere to add spaces to the code provided by Keme? That would enable the alignment of the items. If I use matrix, would I replace "stack" with "matrix"? I am going to try that now. I have not used OO Draw, and so I am going to try that as well.
Thank you everybody!!! I certainly could not do this without you, and my world-changing philosophy paper would never be produced. Now, if I can only find somebody to read it

I tried substituting "stack" with "matrix," and it didn't work. It made a matrix, but all is pretty off. I don't know how to use draw - I have the toolbar up, but don't know how to make objects like this. Is there a way to code spaces?

[dannio]

I got it! The right brace in the "draw" program, is exactly what I need. You guys are amazing!! Thank you so much!!!

Yes! That made more sense of the arrows (and revealed my lack of insight ).
Good catch
