I know, but so much more work!
In any case, I found the solution, description of which is here: Autoscale Graph Problem in Card - #2 by jlfsjunior
It looks like one must explicitly style the graph to be the desired height, and this is best practice across graphs. This can be done either by using either the inline style={“height”: 600px} or by using a className and setting the height explicitly there. I chose to use a className, subtract any difference in the margin and padding, and it came out fine.
Thanks!
