Plan Path and a Actual Path distance calculation

I am using an XY scatter chart that displays the planned path and an actual path as I go. The planned path is set up in 100' increments and goes 12000' and actual path varies along the way.

My data that I use is the Northing (ft), Easting (ft) and Vertical Section (ft) for both the planned path and actual path.

I was wondering if there was an east way to get that information from the chart or if there is a formula that would allow me to calculate distance between the two points by using the data I use for my chart.

Thanks
