Sample 24879: Create a relative average chart
 |  |  |  |  |  |
The sample code on the Full Code tab illustrates how to generate a relative bar chart based upon the average response within each BY group. Upward bars indicate response values greater than the average and downward bars indicate response values less than the average.
