Hello, everybody!

I have a problem concerning plotting two or more graphs in the same window.

What I want to do is a three-curve ECG real-time graphic plotter in one window, so, to understand what I mean, imagine the osciloscope example in the Qwt library with three osciloscopes functioning at the same time, one under the other.

I know that there is an example in the Qwt library which shows how to create more than one graph in the same window, but I couldn't understand its programming (more precisely, I couldn't figure it out where, in the programming, was the code to draw more than one graph).

So could somebody help?

I thanks very much!
