Discussion Board for collaboration on QlikView Layout & Visualizations.
As Rajesh suggested the Gauge charts are dimensional less. Given below is the definition from QlikView help.
"Gauge charts are used to display the value of a single expression without dimensions."
So you may need to revisit your requirement and find out another chart type.
Or you may create multiple gauge charts to compare your dimension values among each.
From the below link you can find that you may create multiple gauges with dimensions in IBM Cognos but I think that may not be possible in QlikView.

PFA, i think this is what you are lookin for,
Plese change the Title font size which will affect your dimension display size
Yay. Many thanks.
