Colors are assigned to new time series on a first come - first serve basis using a standard set of eight colors. When all eight colors are used, the color sequence simply begins again and repeats indefinitely. Each state is assigned a color, which applies to its flow recommendations, graphical windows, and window labels for all systems in the project. If the color of a state is changed by the user, then that change is applied to all instances of that state throughout the project.
The only exceptions to this rule is for the “One State for all Systems” and the “Choose Systems and States” thumbnail plots. In these plot, visual differences between the systems are enhanced by assigning different colors to each system-state series. Color changes in these plots will not affect other plots and, conversely, color changes in other plots will not affect these thumbnails.
To change colors, use the pointer tool and move the pointer over the target time series in the plot. Right click and select "Edit Properties". Color, as well as line style, fill, and line symbols, can be changed. Symbology for imported time series can also be changed via right clicking on the target time series in the data list and selecting “Edit Properties”.
Symbology for time series is initially set per the color sequence at time of first import. Symbology can then be modified by the user, including changing labels (Figure 17). Subsequent imports of already imported time series always use the latest symbology. Symbology for existing instances of time series is not affected by symbology changes.
