The Grid window and the Graph window display time varying results for a single network object. The window is displayed at the bottom of the Baseline Page beneath the Map view.
Values displayed in grids and graphs switch when users switch between runs.
See Viewing Simulation Results for details on generating grid and graph data.
The names of any graphs or grids, which have already been generated, are displayed in the Grid or Graph menus.
Grid Window
The Grid Window displays a grid showing time varying data for a single network object.
The results displayed in the grids are listed below.
If live data is linked to an object for verification purposes, extra columns will be displayed listing the observed values and the difference between the observed and modelled value.
If two simulations are loaded in the GeoPlan for comparison, extra columns will be displayed listing the values for both simulations and the difference between the simulation values.

Trace 01 <node ID> to Trace 10 <node ID> (%) |
The percentage of water at this node that has come via the Trace Node (selected in the New Run dialog when scheduling a Water Quality Simulation). See InfoWorks WS Pro help for more details on water quality options and trace nodes. |

Dominant Source |
Indication of which source contributes the most to water reaching the node, where the sources are Trace Nodes.
This column will only be displayed if there are Trace Nodes selected in the simulation in InfoWorks WS Pro. Only one trace node can be selected in IWLive Pro (see New Run dialog). |

Age of Water (hr) |
This factor gives an estimate of the age of water at various points in the system. This can be used as a rule of thumb measure of underlying water quality. Any new water entering the system at reservoirs or source nodes has age zero, unless an Initial Age of Water has been specified. IWLive Pro calculates the average length of time the water at this node has spent in the system before arriving here. |

| Load (In - Out) | Net rate of inflow into reservoir (Inflow minus Outflow) | RESERVOIR | |||||||||||
| Deficit |
The reservoir may become empty because the outflows exceed the inflows. IWLive Pro Operator Client allows computation to continue with the assumption that reservoir head remains at the reservoir bottom level. The deficit is the amount of water needed to maintain head at that level. |

| Depth | Vertical distance from reservoir bottom level to water level | RESERVOIR | |||||||||||
| Inflow | Rate of flow into the reservoir | RESERVOIR | |||||||||||
| Outflow | Rate of flow out of the reservoir | RESERVOIR | |||||||||||
| Percentage Full | Volume of water in the reservoir expressed as a percentage of available capacity (capacity above minimum operating level). |

Graph Window
Graph results can be displayed for a selected time period by adjusting replay start and finish times on the Replay Options dialog and checking the Apply to Grid and Graph Tools option. Please refer to the Viewing Simulation Results topic for more details on generating graphs.
The red time line display on the graph shows the current time of the simulation, mirroring the current time of the simulation on the Map view. To jump to a different simulation time, drag and drop the red line to the desired simulation time directly on the graph. The simulation date and time will be updated accordingly on the Map view.
If live data is linked to an object for verification purposes, a live data trace will also be displayed when the appropriate parameter is graphed for that object. If the result is linked to verification telemetry (flow, head) then two traces will appear in the graph.
If two simulations are loaded in the GeoPlan for comparison, traces will be displayed for both simulations.
A context menu allows users to change the properties of the graph (Graph Properties option, which displays the Graph Properties dialog) and to export traces to CSV (Export Traces to CSV option).
It can be particularly useful to disable auto scaling prior to switching between runs. For this, right-click the graph, select Graph Properties and untick the Auto scale checkbox.
