3d histogram plot where histogram frequency multiplied by some specific value will be shown in the graph

hist3(X,'Edges',{600:100:5000 5:10:585}) This is the function i have used to plot the 3d histogram where x data is RPM and y data is torque. So here we get the no of occurance of the data in the range specified at the edges as a 3d bar plot. But I want to get the frequency multiplied with .33 and want that result in the plot. How to do that?
