# Graphical Panel Controls: Graph

The Graph control allows you to plot the value of a group of signals over time using a line graph. Signal groups can be configured using the [Signal List](https://docs.intrepidcs.com/vspy-3-documentation/3.9.17/vehicle-spy-main-menus/main-menu-measurement/signal-views/signal-list) or [Signal Plot](https://docs.intrepidcs.com/vspy-3-documentation/3.9.17/vehicle-spy-main-menus/main-menu-measurement/signal-views/signal-plot) features.

Table 1 lists the properties specific to a Graph control. A list of common properties can be found under [Common Control Properties](https://docs.intrepidcs.com/vspy-3-documentation/3.9.17/vehicle-spy-main-menus/main-menu-measurement/graphical-panels/graphical-panels-tools/graphical-panel-controls-common-control-properties).

| SignalGroup | Double-clicking this property will launch the [Expression Editor](https://docs.intrepidcs.com/vspy-3-documentation/3.9.17/shared-features-in-vehicle-spy/shared-features-expression-builder), where you can select a signal group to be graphed.                                                                   |
| PlotSetup   | Double-click here to open a dialog box where various options to control the appearance of the graph can be configured. These are the same as the options found under [Signal Plot](https://docs.intrepidcs.com/vspy-3-documentation/3.9.17/vehicle-spy-main-menus/main-menu-measurement/signal-views/signal-plot). |
