Wallboard Gadget Size

I am experimenting with creating a Jira dashboard gadget that I can display on the wallboard. I’ve started with the “Writing a dashboard item app” tutorial (
and used that gadget for a starting point for my own use.

The problem I’m running into now is with how the gadget is displayed on the wall board. The wallboard seems to want to use a minimum height of ‘300’ which is taking up a lot of unnecessary space. The function calls to resize the gadget in my JavaScript don’t seem to have any effect on the wall board. Any suggestions with how to proceed would be much appreciated. Thanks.
