Scatterplots with obs from different series

[yiagos]

I have multiple time series and I want to create a scatterplot with the observations from all the series. In specific I have for different countries obs for 2 different variables and I want to create a scatterplot for the whole sample.
I group them together and select scatterplot, single graph in pairs, but it is not exactly what I want. I want to treat all obs in the same way and be able to have just one regression line, for the whole sample.

It is difficult to tell from your post the exact structure of your data currently. However it seems that you're describing a panel - you have multiple cross-sections (countries) each with time series data for different variables. That sounds like a panel. If you structure your workfile as a panel, when you graph the two series together, you can choose to stack cross-sections, which will do what you want, I think.
