If I've interpreted correctly:
For example:
Add Sheet1.
In Name Manager put this Dynamic Named Range formula.
Select Q1. Click on Data Validation / Data Validation. In the drop-down list choose List. In the Source select from the Data sheet $C$5:$BQ$5. Click OK. In S5 of Sheet1 enter =dynaChrt and fill down to S39.
Select a chart type. Select S5:S39 for you data source. In your chart choose Chart title. With the Chart title box selected click in the formula bar and type = and then click on Q1. Press F4 key to make the cell reference absolute. Commit with Enter.
Now select from your drop-down in Q1 that you just created. S5:S39 will update and so will your chart.
Is this what you where after?
