Plotting two series of dicreet points with errorbars (std. dev.) on Y and X

I'd like to plot Y1 and Y2 with errorbars, against X (same X for both series) with X errorbars too.

The plot needs to be log-log with a 1:1 refline. Any ideas how I can go about this?

I've tried numerous methods - plotyy with call to errorbar, basic plot, plot and then plot again with hold on. etc etc.

One of the main problems I'm having is the joining of errorbars. I would like discrete points with a simple errorbar in x and y at each point.

Thanks, Dom.

Have you tried:

• barweb bargraph with error bars
• ploterr

Or search on the FEX: http://www.mathworks.com/matlabcentral/fileexchange/?term=error+bars

Thanks for the reply - I have tried ploterr but couldnt get everything right with that. I will possibly keep trying with that as it was close but not quite right - although I've tried so many things today I can't quite remember what the main issue with ploterr was now!

Have you tried errorbarbar, barweb, or barerrorbar along with a line command to get your error bar along the x-axis?
