I see some strange behavior with the property Marker Values for the X and Y scales of a graph. I know what the markers are in the color scale of an intensity graph, but I don't understand it conceptually for X and Y. Does it just refer to the tick marks? That wouldn't really make sense, because those are handled with properties such as "range" and "style". Furthermore, if I look at the Marker Values with a property node, the array is empty, as if it's not used. But if I assign that same empty array to the Marker Values of an identical graph, it makes the intermediate tick marks and values disappear. What's going on?

Well, I can answer part of my own question: If I assign a constant to Marker Values, it does indeed create tick marks and values at those locations, just like the color scale for the Z-axis. It's odd though that the tick marks that naturally occur don't show up in Marker Values. It's like an alternative way to represent the axis. Is this what was intended, or is this a bug?

I do not believe this is a bug. If you look at the help, it is 'an array of user-defined marker values.' Since the defaulted marker values are not user-defined, it will not return anything.

Ok, that makes sense.

I wonder if there is any way to get the marker values that are automatically created.

When using auto-scale for a Waveform Graph, reading from the property node
"Marker Values" gives you an empty array.
How do you retrieve marker values that you want to transfer to a new Graph which may be
a different physical size (and in a different .vi), but you want the same markers ?
