Charticulator Guides - bind to window size?

Hi Henry. Thanks for your response. Maybe I'm mistaken in thinking that the guides needs to dynamically reposition. Linked below is the example, with two copies of the visual (the larger one has the aspect ratio I want, and the smaller one has the right overall dimensions but terrible aspect ratio). 

I imagine I can simply adjust the guide positions manually to get it to look right at the desired size. Is there another way to make it work at the smaller size?
