Some properties are a collection of data values, e.g. Initial Buildup and Snow Pack of Subcatchment as shown in Figure below. A field box and a button is usually given to this type of property. The field box shows the number of rows or name of assigned (in case of snow pack) in the collection data and is read-only. To change the collection data, click the button on the right to open the corresponding editor window.
Some collection editor window (for example, Transect Viewer) has a data table and a graph. The data table is usually on the left of the editor window and it lists all the data records. The graph is usually on the right and it plots the data from the table into a chart. Data could be edited directly in the table or pasted from a spreadsheet software. Context menus are provided to help basic edit operations. Data copy and paste could also be done by using CTRL+C and CTRL+V key. The data plot window will update automatically once the data value is changed in the table.
