Will your book help me with the gauge chart

One of the chart options for the gauge chart is to provide a beginning and ending value for a quality band in order to shade a portion of the gauge.  I know how to do this using the report designer, but this requires me to set the values at design time.  I want to be able to set the values at runtime in VB.Net based on data values that are coming from a database.  Will your book show me how can I use the object model to set these quality band values at runtime?

Unfortunately, I don't cover the gauge chart. I basically show a picture of it and give a few minor details. I never used it. Maybe someone here can offer you some words of advice?
