How to pass a graph to another vi without stripping off the properties????

[altenbach]

You cannot have an array of graphs. One reason is the fact that graphs take 1D and 2D arrays. If you had an array of graphs, how should LabVIEW decide if each array element should be a graph with multiple traces or each trace shoud go into a new array element. 😮

While you cannot have arrays of graphs, you can place the graph inside a cluster container and place that inside an array container. You can have an array of clusters, where each cluster contains a graph. Looks about the same to the untrained eye.  😉

Be aware that array elements only differ in data. All properties are the same. This means that everything, including plot colors, plot styles, axis ranges, etc. are the same for all array elements.

And yes, you can have an array of pictures.
