The following toolbars (available from the main Source screen) allow you direct access to various sections of Source:
- Data Sources toolbar - allows you to add and manage sources of data (time series or by linking to another scenario). You can edit or view this data once it has been loaded in the Data Sources Explorer;
- File toolbar - allows you to create a new project, opening an existing project, and saving a project (and all the scenarios within that project);
- Function manager toolbar - allows you to add and manage all functions and expressions in Source;
- Ordering toolbar - provides quick access to ordering-related functions. The button on this toolbar reveals a pop-up menu;
- Project toolbar - allows you to toggle view of the Project Explorer, Recording Manager, Log Reporter and Chart Recording Manager;
- Recording Manager toolbar - allows you to manage results in the Recording Manager;
- Scenario toolbar - allows you to hide or display the Geographic Editor, Schematic Editor and Tabular Editor, the Function Manager, Data Sources, the Node Palette, the Layer Manager and Location Control panels; and
- Simulation toolbar - allows you to set the analysis type (single, stochastic or flow calibration), specify start and end dates for the simulation, and to run the catchment model.

The Data Sources tab allows you to view and manage time series at one location in Source. When time series are added using the Data Sources Explorer, they are available for use throughout Source. For more details on using this, refer to Specifying data inputs.
Function Manager
The Function manager panel allows you to create, manage and maintain all functions and expressions defined in Source. Just as all data in the Data Sources Explorer is available throughout Source, all functions and expressions added in the Function manager can be used in the same way.
...
Chart Recording allows you to compare the results of different scenario runs. You can change certain parameters in a scenario to see how the output is affected. Refer to Chart Recording Manager for more information on this.

Figure 7. Notes, Overview
Refer to Adding notes to nodes and links and Adding a note to a function for more information.
A summary of all the notes configured in a scenario can be viewed using View » Notes. For the example shown in Figure 16, the Inflow1 node, the $AllocGS function and the Default Link #1 link have notes associated with them.

- You should always include an explicit origin of (0,0). This avoids the need for the model to extrapolate in the negative direction along the X-axis. It also avoids any potential problems which might arise if the model silently assumes an origin of (0,0);
- X-values should always be in monotonically increasing order. In the current implementation, an X-value that is entered out of order is highlighted in red until a Y-value is entered, after which Source re-orders the table. You can use this feature to add interstitial coordinates to a table by adding new (X,Y) coordinates to the last row and waiting for the table to re-order;
- Y-values should also increase monotonically. Be cautious if you need to violate this guideline, and especially cautious if the right-most line segment has a negative slope;
- The right-most coordinate pair should lie beyond your most extreme known value. This avoids the need for the model to extrapolate in the positive direction along the X-axis, and also means that you do not need to remember which piecewise linear editors use linear extrapolation of the right-most line segment vs those which project the right-most Y-value to infinity;
- All values should be sensible. For example, there is no point in entering coordinate-pairs that violate mass balance (eg. a loss exceeding inflows); and
- If your model employs optimised ordering, keep your piecewise linear editors to as few data-points as possible. Complex curves usually increase run-time and can sometimes lead to infeasible solutions. Refer to the chapter on Ordering.
