1. A computer-implemented method comprising: causing display of a graph using an application of a computer, the graph comprising at least two axes and a plurality of graphical elements representing data relative to the at least two axes; receiving user input highlight rules for the graph, the rules including a user input value and an indication that graphical elements of the plurality of graphical elements should be highlighted based on whether a value of a portion of the graphical elements is greater than the user input value or an indication that graphical elements of the plurality of graphical elements should be highlighted based on whether a value of a portion of the graphical elements is less than the user input value; analyzing, using at least one processor of the computer, a value of each graphical element of the plurality of graphical elements, to determine whether a portion of the graphical element is greater than the user input value or whether a portion of the graphical element is less than the user input value, based on the user input highlight rules; identifying, using at least one processor of the computer, a portion of at least one graphical element of the plurality of graphical elements that satisfies the user input highlight rules based on the portion of the at least one graphical element of the plurality of graphical elements that is greater than the user input value or the portion of the at least one graphical element of the plurality of graphical elements that is less than the user input value; modifying the display of the graph to highlight the portion of the at least one graphical element of the plurality of graphical elements to indicate the portion of the at least one graphical element of the plurality of graphical elements that is greater than the user input value or the portion of the at least one graphical element of the plurality of graphical elements that is less than the user input value based on the user input highlight rules; and wherein the modified display of the graph is displayed to the user.
