Cumulative threshold color bars (Figure 1) are commonly used to display cumulative precipitation over time. The following information describes how to assign cumulative threshold color bars to specific CWMS modules:
Assigning threshold color bars to specific CWMS modules:

Figure 1 Cumulative Threshold Color Bars

  1. From the CWMS CAVI main window, open a watershed, click the Setup tab, from the Map Window, click the Time Series Icon Tool. 
  2. Right-click a time series icon, from the shortcut menu, click Edit, the Time Series Icon Editor dialog opens. Click Icon Types and Layers tab.
  3. From the Data Set list, select the data set that you want to display a cumulative threshold color bar in a module.
  4. For each CWMS module that you would like to see a cumulative threshold color bar displayed in the Map window, from the Icon Type list for each module, select Cumulative Threshold.
  5. Click OK, and the Time Series Icon Editor dialog closes.

To set the cumulative threshold values for a threshold color bar:

  1. From the Icon Types and Layers tab (Time Series Editor - Icon Types and Layers Tab), click Threshold Colors, the Threshold Color Bar Editor for Time Series opens.
  2. From the Color Bar Type box, click Cumulative Threshold.
  3. To edit threshold values, from the table click in the cells under the columns Lower Limit and Upper Limit. Enter values as needed. To add rows to the table, from the Edit menu click Insert Row.
  4. To associate a color with that threshold value, click in a cell under the Color column, and a list of available colors appears. Click the color you wish to change, and the color will now appear in the cell of the Color column.
  5. The Applies to box sets the properties for all similar cumulative threshold color bars in the watershed. This Data Set Only is selected by default and sets the properties to only be used by the current data. Parameter sets the property settings to all time series icons using the same selected parameter. Group assigns a name to the properties, which can then be used and assigned to additional time series icon properties. Global Default sets the properties for all time series icons.
  6. Click OK, the Threshold Color Bar Editor for Time Series closes. You will not see a change in the Setup Module, but you will see these changes in the other modules where the time series icon appears as a cumulative threshold color bar.
