Dashboard Chart Descriptions

Good morning,

I need to add chart descipritons into a dashboard I created. Does anyone know of a way to insert a chart description into dashboards, insert a content type into a dashboard below a chart for the purpose of a chart description, or insert code into the charts SQL Query so that the “Query” displaying under the chart will also show the text desired (a chart description)?

I tried entering in /* Text /* into the advanced query, but RT gave me " Wrong query, expecting a AGGREGATOR ".

Thank you for your help.
