How come "overlay" and "stack" are not found in the LabVIEW help?

[gnunes]

In searching the posted questions and answers, I got the vibe that the answer to my problem
might lie in "stacked" or "overlaid" charts.

Imagine my surprise when searching for these words turned up nothing.

(OK, not quite. I do find Plot Multi-XY, but the documentation on that so bare-bones as to be no help whatsoever.)

Documentation faults are common to all kind of programs, not everybody finds what he/she wants, but if you expose your problem, perhaps someone can help you.
Good luck

It's possible the original poster intended to suggest that *you* stack the
plots programmatically in an X-Y plot. It's hardly difficult and is
detailled in the help for the X-Y plot. You say it's bare bones- probably
because you're not understanding this very simple procedure.

If you look at the context help for the terminal of an X-Y graph it tells
you to bundle an array of X data and an array of Y data into a cluster that
represents a single plot. To make multiple plots, you build several of these
clusters into an array and feed it to the XY graph. The XY graph can take
either a single cluster for a single plot or an array of clusters for a
multiple plots.

If you want a "waterfall plot" effect where all the plots are offset in X
and Y then you must add this
offset to the individual arrays before bundling
them.

Thank you for posting comments on the LabVIEW documentation. We're constantly striving to improve the documentation, so any specific suggestions you have are welcome. In the future, please send any comments on National Instruments documentation to techpubs@ni.com so we can address your concerns in a timely matter.

Regarding your specific question, I encourage you to search two locations in the documentation when you are looking for information. You searched the online help, but you also can search all PDF documents at one time. To do so, select Help>>View Printed Manuals in LabVIEW, click the Search button, and type in the word you want to search for. Doing so searches all PDF documents installed with LabVIEW, including manuals, application notes, white papers, a
nd so on.

If you were to search for "overlaid" or "stacked", you would find the following text in the LabVIEW User Manual and a graphic illustrating the plots:

"Overlaid Versus Stacked Plots

You can display multiple plots on a chart by using a single vertical scale, called overlaid plots, or by using multiple vertical scales, called stacked plots. Figure 11-2 shows examples of overlaid plots and stacked plots. Refer to the Charts VI in the examples\general\graphs\charts.llb for examples of different kinds of charts and the data types they accept."

I will make a note of your feedback and we will try to improve the documentation of these plots in the online help.

Again, thank you for your feedback and please send any specific feedback directly to techpubs@ni.com.
