Hi!
I'm migrating from an older data acquisition software for SignalExpress. With the DAQ old had a way to monitor the signal so that the software screen I saw on the timeline and as I increased or diminished the scale of the X axis (time), I saw more or less signal transitions in screen, respectively. For example, if the time scale (x axis) was set to 5 seconds and the signal that I was monitoring commute every 1 second, I would see on the screen of the software 5 sequential pulses.
I am not able to configure my data acquisition that way. What I have noticed is that the scale of the X axis is limited to the value of the "Samples to read." With that, I see the sign on the software screen is instantaneous and not a sequence of pulses.
I intend to monitor the signals are random signals originating from idependentes and switching relays.
In summary, I believe that the solution to what I want to do is increase the scale of the axis X. How to do this?
I use SignalExpress 2011, USB-6363 DAQ step and Digital Line Input.
Thank you.

Are you trying to view your data as a continuously scrolling "strip chart"? In other words, as new data is being logged, it gets added to the chart relative to the time-history.
If this is what you're after you need to turn the waveform data into Scalar data. Do this by adding something like Amplitudes and Levels. Then drag the "DC" signal into the graph. From there you can right click the graph and choose different update modes; strip, scope or sweep chart. If you'd like to increase the amount of data is displayed on the chart before reaching the end of the graph, right click on the graph and change the "history length" to a value greater than what its at currently.

OKors,
First, sorry for the delay in responding to you. And second, thanks for your reply.
I will try your suggestion: continuously scrolling "strip chart".
To try to clarify, what I want is to merge than I can with Digital Graph - signs lined up vertically with the display type Chart, where it can act on the parameters of History Lengh, as you suggested, to achieve "curb" the transition graph .
If using the first solution, Digital Graph, the screen transitions are very fast. On the other hand, if using the graph chart type for digital signals, they overlaps, since all have the same value - 0 or 1.
The idea is that these two characteristics in a single graph (Data View). I believe something to be simple, but I'm having trouble mounting this setting.
That's it. Any news ... I'll post here.
