1. A computer-implemented method, comprising: accessing, on a computing device, one or more anchor images, one or more area of interest parameters, and one or more hotspot parameters; receiving display data including contents of a display; identifying an area of interest in the display using one or more anchor images and the one or more area of interest parameters, wherein the area of interest is identified as an horizontal area between two points associated with an image, a vertical area between two points associated with one or more images, or an horizontal area and a vertical area between two points associated with one or more images, and wherein the area of interest is identified by searching the display in a horizontal or a vertical direction from a point associated with an image; receiving a hotspot anchor image; determining a hotspot anchor point by graphically matching the hotspot anchor image to the area of interest; determining, on the computing device, a hotspot within the area of interest using the hotspot anchor point and the one or more hotspot parameters, wherein the hotspot is defined relative to the hotspot anchor point; and determining one or more data values corresponding to one or more positions in the display, wherein a data value is determined relative to the hotspot.
