Managing Cases

Data Desk displays cases consistently in every appropriate place. Cases have three properties. These are kept up to date dynamically if they are changed in one display or window, they change in all others simultaneously. These properties are:

Selection

Points in plots indicate selection be becoming larger, brighter, or darker. Cases in editing windows indicate selection as they ordinarily would for editing (and are selected for editing.) Portions of some displays (such as histograms and bar charts) show selection with a ‘sub-display’ of the selected cases.

Tools to select cases are found in the Plot Tools palette.

Color

Cases displayed as points (e.g. in scatterplots, dotplots, parallel coordinate plots, etc) can be displayed in any of 64 colors. The color of a case is consistent across all such plots. You can assign a color to a point by selecting the point in a plot and clicking on a color in the color palette. Colors can also be assigned by case (in a categorical variable) or value (from a quantitative variable.)

Symbol

Cases displayed as points (e.g. in scatterplots, dotplots, parallel coordinate plots, etc) can be displayed with one of 8 symbols. The symbols are selected to be as different from one another as possible.
