A thumbnail plot (Figure 1) is a miniature version of the full-size plots available in HEC-RTS, showing data for the duration of the time window. The thumbnail plots the data. You can set the color of the curve that represents the data.

Assigning thumbnail plots to specific HEC-RTS modules: 

  1. From the HEC-RTS CAVI main window, open a watershed, click the Setup tab.
  2. From the Map Window toolbar, click the Time Series Icon Tool.
  3. Right-click a time series icon, from the shortcut menu, click Edit, the Time Series Icon Editor dialog opens.
  4. Click the Icon Types and Layers tab (Time Series Icon Editor - Icon Types and Layer Tab).
  5. From the Data Set list, select the data set that you want to display a thumbnail plot for in CWMS modules.
  6. For each CWMS module that you would like to see a thumbnail plot displayed in the Map Window, from the Icon Type list for each module, select Thumbnail Plot. For example (Time Series Icon Editor - Icon Types and Layer Tab),for the Visualization module, for the selected data set, a thumbnail plot will be displayed. 
  7. Click OK, the Icon Data Set Editor dialog closes, and the assignment will be saved. Each data set assigned as a thumbnail plot will be assigned a color each of its displayed curves. However, these colors can be changed, which is described in the following section.

To set the scale of a thumbnail plot:

  1. From the Time Series Icon Editor dialog, click the Icon Types and Layers tab (Time Series Icon Editor - Icon Types and Layer Tab).
  2. The Thumbnail Scale group box represents the minimum and maximum values displayed with in a plot. To set these values, first check the checkbox next to Min or Max, and the fields next to the labels will become enabled. Once the fields are enabled, enter the numeric values for the items you selected.
  3. Click OK, the Time Series Icon Editor dialog closes. To save the changes to the watershed, from the File menu, click Save Watershed.

A curve is created for each data set that is assigned as a thumbnail plot. For the example, in Time Series Icon Editor, three data sets are assigned as thumbnail plots, so three curves are listed. However, depending on what parameter set to display in plot, all curves may not display at once. The colors are assigned to the curves in the order they were associated with the thumbnail plot.

To set the color of the curve on thumbnail plots:

  1. From the Time Series Icon Editor dialog, from the Data menu, click Icon Plot Colors. The Plot Icon Color Editor opens (Figure 2).

  2. Under the Curve column, a number is assigned to each data set that has been defined for the time series icon.
  3. To change the color of a curve, click in a cell under the Color column and a list of available colors appears.
  4. Click the color you wish to change, and the color will now appear in the cell of the Color column. Click OK, the Plot Icon Color Editor closes. You will not see a change in the Setup module, but in any of the other modules where the time series icon appears as a thumbnail plot, the color change will appear.
