Waveform graphs

“

- [Male Narrator] Waveform graphs differ from waveform charts in how they display and update data. While charts are good for visualizing data that's accumulated point by point over time, if you need to visualize an entire set of data all at once, you should use a graph. Unlike the chart, which maintains a buffer of previous points and can accept data as single points or arrays, the graph only accepts arrays of data in various formats and then plots all received points at once. The waveform graph is located on the controls pallet in the graphs menu next to the waveforms chart. Now, as a data source for this example, I'll add a random number generator from the functions pallet numeric menu and I'll wire that to the waveform graph. Notice that it gives me a broken arrow. Unlike the chart, the waveform graph cannot accept individual data points which is what the random number function produces. So, let's use a for loop to…
