Hello All.  
Has anyone created a way to grab a range of data from a chart and totalize the values from it? I need to create a TOTAL GALLONS value from flowmeters rate values that are being stored every second.  
Client is hoping to select a range on a chart and have a total gallons valve displayed.

Any ideas?

Thanks
