Dashboard needs to update to include newly added fields names and counts...

I'm working on a dashboard that displays the Defect category or sub-category plus the count of defects within that category and sub-category.

Currently, I have to manually go into the dashboard and update it when a new sub-category is added. What I like to have the dashboard do is add that new sub-category and count dynamically. I have included a screenshot of the section of my dashboard below.

Plus, I'm open to suggestions on a better way to display this information, charts may be a way but with the titles so long it's hard for the user to understand each out. Plus, we are getting ready to add about 18 more sub-categories.

All suggestions and help is greatly appreciated.
