Display Panel

The Display panel provides control over the way cases look in an open collection. Using these capabilities, you can create fun, visually interesting, and illuminating displays of data. See Change the Appearance of Cases in a Collection for details.

•x and y determine the position of the center of the icon in the open collection. The coordinates (0, 0) refer to the point in the upper left of the open collection rectangle. x increases to the right; y increases down.

•The image attribute refers to the icon that is displayed for a case. You can only change the image by writing a formula; that is, you can’t type the name of the image you want. The formula editor contains a list of available icons. To bring back the gold balls, set the formula for the icons to the empty string (""). The cardIcon function (see Probability of a Pair) is designed to be used in the formula for image. A sample document, IconList, shows a complete list of available icons with their pictures and names.

•width and height refer to the size of the rectangle in which the icon is displayed. Although you can make the width and height bigger than 32, picture icons will not look very good at larger sizes

•.caption refers to the text that appears below the icon. If you make the formula the empty string (""), there will be no caption. Choose Table | Use as Caption to change the formula for a caption to be the name of one or more attributes. A useful function for captions is concat, which allows you to concatenate up to ten items. For example, concat( name, " is ", age, "years old.") would produce captions like “Stan is 16 years old.” with individual names and ages substituted for each case’s caption.

Many of the sample documents make use of Fathom’s ability to make data-driven collection displays.
