Errorbars on two seperate curves starting from a particular point

I have

1. data files of two curves from 0 to 2.5
2. data file of another curve from 0 to 2.5
3. I want to plot first two data files from 0 to 2.5 and third data file as error bars starting from 1 up to 2.5 on the first two curves.

Would anyone be able to help me in this regard. I need it urgently.

Thank you.

And what have you tried and where did you have a problem? Seems straightforward enough...but w/ no data not much to do unless try to create your problem for you...

I think the command you are looking for is:

errorbar(x,y,neg,pos): draws a vertical error bar at each data point, where neg determines the length below the data point and pos determines the length above the data point, respectively.
