Alter axis size with broken axes

[sfridy]

Hello,

Hopefully a simple ask but I'm looking to adjust how much space each section of my y-axis take up in my graph after splitting. The goal being to stretch out the bottom half more to better see changes. Is there way to dictate that that each section of the y-axis take up say 50% of the graph? So, min-630 take up 50% of the graph and 4699-max take up the other 50%.

Thank you

As a suggestion, why not use both both y-axes if the sole purpose is to better see the changes? The code is even simpler than it would be to allocate 50 percent of a single y-axis?

proc sgplot data=test;
	vline week /response=var1;
	vline week / y2axis response=var2;
run;
