Embodiments of computer systems for visualizing information and data from samples, such as nucleic acids, proteins, or other bio-polymers, are disclosed. One embodiment of a method comprises displaying first and second display areas on a display, displaying an axis dividing the first display area into first and second sub-areas, and displaying first and second axes, wherein the axes are substantially perpendicular to each other. The method further comprises displaying a plurality of bar graphs in the first display area, wherein a length of each bar graph in the first sub-area corresponds to the scalar data information of a first biological sample, and a length of each bar graph in the second sub-area corresponds to the scalar data information of a second biological sample; displaying, in the second display area, a plurality of markers, wherein each marker is related to one of the bar graphs.
