A method to display time-variant information that includes displaying, for example, on a computer-generated user interface, a common baseline value indication (or representation) for multiple data items. The common baseline value indication represents respective baseline values for each of the multiple data items (e.g., stocks) at a first instance in time. The method includes displaying deviation indicators (or representations), relative to the common baseline value indication, for each of the multiple data items. The multiple deviation indicators represent respective deviation values, relative to respective base values, for each of the multiple data items at a second time instance. Each of the deviation indicators may further visually identify a respective deviation value as being positive or negative, relative to a related base value.
