Igro Pro NIDAQ viewing

Hi to everybody!

I'm building a laboratory for electrophysiology using NIDAQ Igor Pro software. I've been checking the different ways of viewing a signal on-line, namey in real-time. Now I'm watching the signal using "Wave Scan" in mode "Repeated". I'm watching the signals inside a window of a chosen length, for instance 10 seconds, and then, after this time, the signals goes back to the beginning of the window and starts again to draw. I'd like to watch the signals as in real oscilloscope, that means, in a continuous way, without coming bacjk to the beginning, because I could miss some important spikes in this instant of conmutation. Is this possible? Thank you very much!
What you describe sounds to me like a chart control and FIFO. See the NIDAQ Tools MX help subsection "Continuous Analog Input into FIFO's" in the NIDAQ Tools MX Guided Tour, or the Analog Input: Using FIFOs in the Programmer's Introduction.

I have written a data acquisition and analysis package for Igor, used by neurophysiologists, that supports NIDAQ devices and has this feature. I use it in my own experiments for a "seal test" when doing patch clamp recordings of neurons. I can share some code with you, and if you are interested we can discuss the whole package.
