C (?), no, you are right it is B @ dfjuggler: Answer A is the "transposed array" option on, so it is (in my opinion) not the original output/result even it is the default case. I recognized it after coding this example. I still think B is the answer. (sorry for my limited English)
@Andreas23: I also later checked by coding, but I got A by default. At the same time, from the help: "If you cannot determine the number of plots you want to display until run time, or you want to pass multiple points for multiple plots in a single update, wire a 2D array of numeric values or waveforms to the chart. By default, the waveform chart treats each column in the array as a single plot. Wire a 2D array data type to the chart, right-click the chart, and select Transpose Array from the shortcut menu to treat each row in the array as a single plot."
On the other hand, I'm a bit confused since I get B only after deselecting Transpose Array, which is selected by default when I wire the 2D array. This seems to be the opposite to what the help is describing.
