List View

A list view is a simple spreadsheet-like viewport that is totally integrated with the rest of Argos and can be generated by the List button in the console or by the mode.

Each column corresponds to a variable of the data set being visualized. The number of columns is printed at the bottom of a list view. For example, there are 19 columns in Figure 11-14.

Each row in a list view represents an observation. The number of observations in a list view is printed at the bottom. For example, the number of observations in Figure 11-14 is 19276. You can paint rows in a list view and the icons of the painted observations in other viewports will update their colors accordingly. The effect of painting done in other viewports will show up in list views that contain the same observations. You can also retrieve data from a list view, send the retrieved data over to the temporary console, and carry out further analysis.

The ordering of rows from top to bottom in a list view is initially the same as that of observations in their original data set. Clicking the left mouse button over a column label will order rows from top to bottom in increasing order of the clicked variable unless rows are already ordered by the clicked variable. When rows are already ordered by a variable, clicking that variable again will reverse the row ordering. For example, the list view in Figure 11-14 will look like the one in Figure 11-15 after the Nucleus Area column label is clicked.

If the same column label is clicked again, the list view in Figure 11-15 will look like the one in Figure 11-16.

To restore the original ordering, do Shift-Left over the column label displaying a black triangle.
