control figure size of export from graph builder

[#1]

I am in Graph Builder and am having some difficulty exporting the figure the way I would like it to look, specifically.
1. the number at the top of the y axis is cut off halfway through the number. It looks like the portion under the Graph Builder bar is not exported.
2. I need to set the x-y ratio and size so that the exported fonts, lines, and markers are the size I would like them to be. It currently seems that they scale with the size of the window. Is there a way to set the size of the exported image so that the figure has a set size that can be controlled by entering in numbers? Where is that located?

Thanks, trying to get publication level figures out. Will be using EMF but eventually may need to go to TIFF. 

Any help will be appreciated.

How and where are you exporting the figure? How does your figure look like in JMP?

I'm using windows 10 and JMP18.0.1 and I usually do this (better methods most likely here Getting high-quality graphics out of JMP )
