You can make a picture of a 2D data array that you can display in picture out. draw area size is a cluster containing width and height, it can be obtained from the attribute node of a picture control or indicator (this allows for rescaling of the actual picture control or indicator). plot number controls which waveform should be visible in the picture. With the array highlight you can specify a selection that will be shown in red on the blue plot. settings is a cluster containing values for the maximum voltage on the y-axis, the time zoom factor and the time scroll factor. origin is a cluster containing the pixel values of the origin of the graph, scale is a cluster containing the x- and y-scales of the actual picture created. These outputs can be used to transform pixel data as obtained from the mouse attribute in to real time voltage values with FLCWFG Mouse Position to VT.vi.
