Selection thresholds in a visualization interface

A product comprising a tangible, non-transient computer usable medium having computer readable program code thereon, the code being executable by a processor and comprising:

• program code for displaying a plurality of data sets within an interface, each of the data sets comprising data from one or more data points wherein each of the data sets;
• (i) is associated with a different selectability value;
• (ii) defines a boundary, and
• (iii) has a different order within the interface, wherein boundaries of two or more data sets overlap within the interface to define an overlapping portion;
• program code for receiving a selection of a threshold selectability value;
• program code for receiving an input, within the interface, at an input position within the overlapping portion of two or more data sets, the two or more data sets that have the input position within the overlapping portion defining potentially selected data sets;
• and
• program code for determining, in response to the input within the overlapping portion of the two or more data sets, one or more of the potentially selected data sets within the interface that satisfy the threshold selectability value,
• wherein determining includes identifying a first data set positioned at least partially underneath a second data set, the first data set having a selectability value that satisfies the threshold and the second data set having a selectability value that does not satisfy the threshold.

An apparatus for displaying data, the apparatus comprising:

• a graphical user interface configured to display a plurality of data sets within an interface, each of data sets comprising data from one or more data points, where each of the data sets (i) is associated with a different selectability value, (ii) defines a boundary, and (iii) has a different order within the interface, wherein boundaries of two or more data sets overlap within the interface to define an overlapping portion;
• a receiving input operably coupled to the graphical user interface, the receiving input being configured to receive input at a position, within the interface, at an input position within the overlapping portion of the two or more data sets, the two or more data sets that have the input position within their boundary defining potentially selected data sets;
• and
• a selector operably coupled with the receiving input, the selector configured to select, in response to the input within the boundary of the two or more data sets, one or more of the potentially selected data sets within the interface that satisfy the threshold selectability value,
• wherein selecting includes identifying a first data set positioned at least partially underneath a second data set, the first data set having a selectability value that satisfies the threshold and the second data set having a selectability value that does not satisfy the threshold selectability valued.
