Plotting Xt against Xt-1

Hi,

I am looking at unemployment figures and have fitted a ARMA model to the data. I need to plot the residuals with the y axis as "xt" and the x axis as "xt-1". Any idea how I would go about doing this, I can't seem to get it to work out.

Thanks.

Meant to add that I am using Eviews 6 and also I assume it is a lag plot that I am trying to create

Create a group with RESID and RESID(-1) in it. Then graph the group with an XY graph.

Thank you for your reply.

Pardon my ignorance, but how do i create a RESID(-1) series - can I do this in Eviews or do I need to do it in Excel and import the data?

You don't need to "create" it. When you create the group and need to list the series you want in the group, just enter "RESID" and "RESID(-1)"
