Although these Aspen Dynamics plots are useful to see what is going on during each run, they have a fixed structure (multiple variables per plot) and do not permit comparisons of results from different runs. Fortunately, this is easily handled by storing the data in a file and then producing your own plots using your favorite plotting software. To store the data, right-click the plot and select Show as History. Figure 7.39 shows the resulting table, which can be copied and pasted into a file.
