Align Y axes on multiple bar charts

[nat-jones]

Question

I have a page in my app that displays 2 bar charts stacked vertically. They both have the same domain, but ranges of much different magnitude. If you look closely, you can see that the y Axes do not quite line up vertically because the unit strings on the bottom chart are longer and push the chartArea slightly to the right. Is there any way to control the width of the y axis labels so that I can line these charts up perfectly?
