Charts work something like realworld paper chart recorders. You can't move one plot ahead of the other. You can append data to the various traces at the same time, but you can't rewrite history or into the future. Graphs on the otherhand can do pretty much anything you like, but it may take some programming. And then there is the combo. If you open up the example/general/graphs/gengraph.llb/Scanning Chart with History.vi, you will see that this example uses a chart to show the incoming data, and the history is drawn on a multiplot graph. When the chart finishes a channel, it clears and the data is rotated into the graph. Greg McKaskle
