Calculating Area Under Curves & Plotting Output on Same Graph

[#1]

I'm trying to find out how to calculate the area under a graph in JMP. In the past there have been a few questions about this but nothing seems to answer the question I have fully

This answer is good for plotting the fit x by y and getting the curve formula - or I could use the nonlinear platform to do a similar job Formula for polynomial function / Finding Area under the Curve 

There is also one somewhere where the script seems to have stopped working ( I have seen it but can't find it again).

Is there a way to calculate the area under curves in JMP ( using Simpsons rule??), give me the area and plot the output ( histogram style) using a JMP script? I've included a basic example of a table which produces these similar plots but the differences could be important for further analysis

Regards

My addition to this recent thread should help.
