Gadget does not show title in wallboard mode

Summary

When viewing certain content such as the average age gadget in the wallboard, you cannot tell what filter the graph belongs to as there is no title containing the filter name.

Steps to Reproduce

1. Create a dashboard
2. Add an average age gadget
3. View as wallboard

Expected Results

The filter name should be included as a title, so that the chart is identifiable amongst other similar charts.

Actual Results

There is no title provided for the gadget

Workaround

There is a workaround to enable the Text gadget and add it next to each chart: Gadgets Jira applications.
The text gadget is disabled by default because it is a potential security risk, as it can contain arbitrary HTML which could potentially make your JIRA system vulnerable to XSS attacks.

1. From the apps administration page, enable the Text module under the Atlassian JIRA - Plugins - Gadgets Plugin
2. Add the Text gadget next to each gadget in your dashboard
3. Add a title, and in the HTML field enter a gadget title, for example:

   <h1>Created vs. Resolved</h1>
   

4. Place the title next to it's corresponding gadget, and edit the layout if necessary
