Moving average of volume in Metastock

Can anyone tell me how to plot moving average of on volume bars itself, the way it has been done in this link http://www.stockcharts.com/education/ChartAnalysis/doubleTop.html
thnx & regards

Naveen,

It's as simple as plotting MA on the price chart. Drag the MA from the indicator list and place it in the volume window. When your MA will be placed in the volume window, the volume bars will turn pink, an indication that you are at the right place. Leave the mouse button and u r home.
