Methods and systems are provided for cognitive behavioral therapy. A first set of data and a second set of data related to a health attribute are received, over a first time period. The first and second sets of data are displayed in a first and a second graphical item. A graphical button is displayed on the first graphical item and configured to move it on a display. Using the graphical button, the first graphical item is, at least partially, overlaid upon the second graphical item. In response to the overlaying a third set of data is generated and displayed in a third graphical item. The third set of data is at least partially based on associating the first set of data with the second set of data using one or more sets of rules that establish the relationship between the first set of data and the second set of data.
