. Figure 7-6 shows a simple buffered input application that
uses graphing.

Simple Buffered Analog Input with Graphing
For a 2D array to be displayed on a waveform graph, each row of data must
represent a single plot. This is because waveform graphs are in row-major
order. Because the channel data is in each column, you must transpose the
2D array. Transposing the array can be done easily by popping-up on the
front panel of the graph and choosing
Transpose Array
