I have two worksheets in one dashboard and as you can see the axis does not match up! My goal is for them to constantly be aligned all the way across, the far left box data is the manager and everything to the right are the stores. As you can see the scales shift if word wrap is on. That's fine unless the manager name does not need to word wrap or the manager name does but the store names do not. The only workaround I came up with is take the word wrap off of both the manager name and the store name but then of course the names get truncated.
Check out the help videos for formating and placing dashboard objects here - Dashboard Objects
I believe these will help you by showing the way to place fixed size objects on the view. one other option is for the box for the manager name or text be a separate view that is placed on the view as a Floating view.
