MS Excel Add-In

A graphical editor has been added for editing time series data. The editor displays an editable plot of the data on the top and a scrollable table of the data on the bottom of the editor window. You can edit data in the graphical editor by drawing a curve with your mouse, or by selecting a point on the curve and moving that point up or down, or by changing a value in the associated table. You can also have the editor linear interpolate missing points, or use the other fill options associated with tables. A complete description is provided in Chapter 4 of the User’s Manual.

The tables have been improved for data editing and better pasting functionality for data entry. The data entry windows now have a paste button to copy data from the clipboard directly into the table. This makes transfer of data from other programs, such as Microsoft Excel, an easy copy/paste task. You can also access the graphical editor for time series data directly from the data entry window.

The math functions have been improved. You can now perform operations on many data sets at one time by selecting those sets from the list in the math functions window. For example, you can estimate missing data for all of your data sets at one time, instead of having to work with individual data sets. The Time Conversion operations have been improved to be easier and more useful. For example, computing the dates and values of annual peak flow for a multitude of daily data sets can be accomplished in a single clear operation.

A “plug-in” capability has been added that allows user implemented code to directly access the functionality of HEC-DSSVue. A plug-in is a set of Java software that is compiled and put into a Java “.jar” file. By simply placing this file into the HEC-DSSVue Plugins directory, it is automatically loaded and accessible from the HEC-DSSVue program. Typical uses for plug-ins are: complex mathematical operations; specialized formatting of data for entry into another application (such as a program that uses a “card format”); and, retrieval of data from a web site. Current publicly available plug-ins include a USGS data retrieval plug-in and California Data Exchange Center (CDEC) data retrieval plug-in.
