Hello! I am trying to fill the area under a plot using patch
the X values are stored in a 1x1823 matrix called serrN_eg and the Y values are stored in a matrix called closestapproach which is also 1x1823. The problem is that the area is filled diagonally but not the area under the line. The command I am using is:
patch(serrN_eg(1:1823),closestapproach(1:1823)./1e3-2634,'blue')

We don't have your data. Make sure that the (0,0) point is in your data sent to patch(). Looks like now, that point is not in there so the patch does not run over there to include it in the colored region.
