I am trying to plot only the lower error bars. Here is the way I am currently plotting them. Any suggestions?
residual = N - y_new;
errorbar(x_new,y_new,residual)

Not the prettiest method as it leaves the bars in but you can set the lower and upper side individually, i.e.:
errorbar(x_new,y_new,residual,zeros(size(residual)))

Try this:
errorbar(x_new,y_new,residual,[])
It specifies that the lower error bar is to be plotted and the upper error baar is not.

residual = N - y_new;
errorbar(x_new,y_new,residual,[])
Input arguments for four inputs are:
errorbar(x,y,neg,pos)
If only three arguments, then the third is the error magnitude in both directions.
