How do I plot only the lower error bars?

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)))

Answer 1

[Star Strider]

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.

Answer 2

[dpb]

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.
