This chapter describes the creation, configuration, and management of time series icons layers. When you create a new watershed, a default layer called Time Series Icons (Figure 1) is created. This layer includes all of the time series icons that you define for your watershed.

Figure 1 Map Layers Dialog - Time Series Icons Layer

You can create additional time series icons layers to separate time series icons by data type. For example, a gage may report stage and precipitation (and compute flow from stage). You can create layers for each of these data types and name them, for example, Stage, Flow, and Precip. Creating additional layers allows you to focus on the specific data type you wish to see.

Creating Time Series Icons Layers

To create additional time series icon layers: 

  1. In the Setup module, click the Maps menu. Select Map Layers. The Map Layers dialog will open (Figure 2). From the Map Layers tree, right- click Time Series Icons. From the shortcut menu, click Add Icon Layer, and the New Time Series Icon Layer dialog opens (Figure 3).

  2. In the Name field, type a name for the sub-layer. For example Flow, Stage, or Precip. 
  3. In the Description field, type an optional description for the sub-layer.
  4. To add all of the time series icons that you defined for the watershed to the layer, check Add all Time Series Icons' Data Sets to this Layer. If you want to add individual time series icons to the sub-layer, clear Add all Time Series Icons' Data Sets to this Layer. For more detail on how to add individual time series icons to sub-layers, see Time Series Icons.
  5. Click OK, and the New Time Series Icon Layer dialog will close.
    Another way to access the New Time Series Icon Layer dialog is from the Icons Types and Layers tab of the Time Series Icon Editor shown in Figure 4. To access it, use either the Select Tool or the Time Series Icons Tool to right-click on a time series icon in the Map Window of the Setup Module. Then, select Edit, and click the Icons Types and Layers tab. Click the Add button at the lower left, which will open the New Time Series Icon Layer dialog (Figure 3).

    The new time series layer will appear in the Map Layers tree (Figure 5) and in the Layers list on the Icons Types and Layers tab (Figure 4). Repeat this process for all layers that require separate control. 
    When you are done creating Time Series Icons Layers, you can specify datasets for individual time series icons layers (for more details on how to configure time series icons see Time Series Icons). Figure 5 Map Layers Dialog - Time Series Icons Layer - Flow

Removing Time Series Layers

To remove layers: 

  1. From the Layers list on Icons Types and Layers tab (Figure 4), select the layer you wish to remove, and click the Remove button at the lower left.
  2. A warning message dialog will open. Click Yes, and the layer will disappear from the Layers list on the Icons Types and Layers tab.
