About The Legend

The legend is a graphical representation of all the map layers in the current project. The default position of the legend is docked on the left hand side of the screen. The legend offers layer manipulation functionality including but not limited to changing a layers symbology or its z order in the drawing process. The legend also supports the grouping of layers, and the toggling on or off of themes within a layer.

Below is a sample screenshot of the legend:	Below is a sample right click over a map layer within the legend:

Legend Functionality

The legend displays its information in the following format:

• First square: [+] This indicates that there is additional information regarding this layer that is currently hidden. This can be exposed by clicking on the [+] symbol.
• Second square: [ ] This indicates whether a layer is always visible (checked), always hidden (blank) or is scale dependent (grayed). This status can be changed by clicking on this square to toggle between visible and hidden. However, to change scale dependence this needs to be done from layer properties.
• Text: This is the name of the layer. Double click this text to bring up the properties of the layer.

Additional Layer Information

Each layer may have zero or more themes associated with the data. By looking at the streets layer in the example image above the legend indicates that this layer has six value themes and two label theme associated with it. The last value theme has been expanded to show additional information about the theme. Each theme can be toggled on or off individually by clicking the checkbox next to the theme name. Within a value theme, each individual value can be toggled on or off by clicking the checkbox next to the value. To see the properties of a theme, double click on the theme name.

Grouping Layers

Layers may be grouped so they can be toggled on or off as a group with a single mouse click. To group layer first select the layers to be grouped in the legend. Hold down the control key to select more than one layer. Once the layers have been selected, right-click the mouse over one of the layers and select Layer Grouping and then Group Layers from the popup menu. Enter a name for the group. To ungroup layers, right-click over the group and select Layer Grouping and then Ungroup Layers from the popup menu. To rename a group, right-click over the group and select Layer Grouping and then Rename Group from the popup menu.
