Hallo,
I want to show the change in surface elevation, due to subsidence, with time of several periods as a chart in Excel.
I woul like to have along Y the periods of time (2001-2003, 2003-2005, 2005-2007, 2007-2009).
And along X, the surface elevation. I have the surface elevation data of the subsidence as (X, Y, Z) of points along cross sections going through the subsidence for each period.
I want to have the graphs for the four periods in one chart that I can compare them to each other and show the change in the surface.
How to do it??????????????
Thanks
Rose
