I want to plot a line graph showing how elevation changes along the x or y axis. I want to be able to control the x or y intercept and see how elevation changes across a transect. I have x,y and z data which has been interpolated using
xi=linspace(min(x),max(x),1000) yi=linspace(min(y),max(y),1000) [xi yi]=meshgrid(xi,yi) zi=griddata(x,y,z,xi,yi)
Is there an easy way of producing simple plot line graphs that show how elevation (z) changes along different transects (e.g yi = 20,25,30,35,40).
Any help would be much appreciated!
