How to prepare a 'scaled' 2D plot?

I have values of a variable like v, which change with y, at different x stations.

I'd like to have a plot similar to this: http://imageshack.us/photo/my-images/713/plotj.jpg/

I am wondering how I can do this MATLAB? The tedious way is to manually scale v and then add it to x and plot new x with y! But I guess there is some automatic way to do this.

Any help would be appreciated.

Thanks.

I've made a plot similar to this, and I had to do the tedious way as well--basically add a scaled version of the deviation (lines with points) to the x values, and then plot the new x vs. y. I don't think there is a more automatic way to do this to get your style of plot. The only way I can think of would be to use quiver() to represent your deviations as arrow lengths.
