Histogram Chart Needed

I am trying to use a vertical bar chart to create a Histogram. Though BIRT has built in STD Dev functions, I am not yet able to find a way to create this chart. In other words simply adding a data binding, with the birt function STD Dev aggregation on MonthToDate Returns doesn't do it for me. 


Basically I need a normal distribution along the x-axis and the y-axis will hold the values for the MTD values.

I am trying to get the Normal Distribution chart.


Any ideas?
