If the backlight works it's likely you connected it correctly.
The results follow, however, they are the same whether the hat is installed or not. As I mentioned above, I already had an IMU wired into the dAISy board.

What is really needed is documentation that explains how to hook everything up. I find Openploter to be very fragmented and unfriendly to the user. If it is to ever get beyond the programmer level, it will need to be simplified. For instance, I thought Pypilot was a plugin for OpenCPN. But there is a standalone and openplotter versions too, I guess. I don't really know what I am working with. How do these pieces fit together? What is the slave and what is the master?
