Multi Y-Axes

When you first use DAQ Plot, you should configure it with the minimal amount of amplitudes. You do that by these steps:

First configure your Hardware device. During configuration, turn off all channels that will not be use. You do that by unselecting the switch next to each channel settings (make sure to click Apply after your changes). Typically hardware collects signals (voltages) from a group of screw terminals, say one through eight. It collects those voltages one at a time by multiplexing a single analog to digital converter, thus the collection is serialized and as such each signal you collect delays the collection of the next signal.
You can also combine hardware via the Meta preferences. The Meta device multiplexes the channels of hardware into one contiguous sequence of channels.
Once you are collecting data from your hardware then use the Derived preferences to synthesize the data into other groups of data. This may result in a decrease or increase of number of amplitudes.
Use the Data preferences to remap voltage units to physical units.
Most likely, you are simply using one piece of hardware and all you need to do is connect voltage signals to the connectors and start plotting, but the above shows how there can be more complex situations that result in the collection of many signals.
On the main window (and spectra window) turn off all unused amplitudes by setting the y-axis index to Off.

The result of the above is probably a bunch of no-ops. That is: You simply want to plot a voltage. However, it may be that your amplitudes represent different units such as force, displacement, logic states, intensity of light or other things. In that case, the y-values may have very different scales and it doesn't make sense to plot all the curves on one y-axis. For that situation, there is the multi-y-axes representation. Use the Y-Axis pop up buttons on the main interface to associate the amplitude index (curve index) with the y-axis index. y-axis indices are numbered from in to out in sequence, that is: 1 is the left axis, 2 is the right axis, 3 is the 2nd left axis, 4 is the 2nd right axis and so forth. You should make the amplitude to y-axis mapping in such a way that all consecutive y-axis indices are used.

The figure below shows one such example.

The curve colors and y-axis title colors have been set to show the relationship between data and y-axis. Moving the cursor over the curve will also show that relationship in a pop over.

In order to format the graph with minimum y-direction size, click on a y-axis index pop up button. That will refit the graph at that time. The refit depends on the current axes limits so you may want to refit every so often. As your need for y-axes increases so will your screen size. You may need to make DAQ Plot's main window very wide to accommodate all of your y-axes.

Ultimately, you may wish to export the plot to Graph IDE. For that make sure the Signal (or Spectra) window is the key window and then choose the Export ► Plot To Graph IDE menu item. Your plot will be exported to Graph IDE (if installed on your computer). From there you can reformat the graph. I mention that because multi-y-axes is a very graphical representation and has many attributes that are preset and many more attributes that can be fine tuned.
