Data plot processing

A computer program product for processing a data plot comprising a plurality of data points for inclusion of additional information content, the computer program product comprising a non-transitory computer readable storage medium having program code embodied therewith, the program code executable by a processor to perform a method comprising:

• dividing a space of the data plot into subspaces, wherein each subspace contains at least one data point of the data plot;
• computing an available area on a display for each subspace;
• computing a compressed information representation for each subspace based on information about said at least one data point contained in said each subspace and a computed available area for said each subspace;
• computing an available area of said each subspace based on a maximum size of a shape that can fit within said each subspace, wherein the shape is centered on a barycenter of said each subspace;
• and
• displaying the data plot with the compressed information representation for said each subspace, wherein each unit of compressed information is displayed on the display adjacent to a corresponding group of data points from the data plot.

A computer system comprising:

• a processor, a computer readable memory, and a non-transitory computer readable storage medium;
• first program instructions to divide a space of the data plot into subspaces, wherein each subspace contains at least one data point of the data plot;
• second program instructions to compute an available area on a display for each subspace;
• third program instructions to compute a compressed information representation for each subspace based on information about said at least one data point contained in said each subspace and a computed available area for said each subspace;
• fourth program instructions to compute an available area of said each subspace based on a maximum size of a shape that can fit within said each subspace, wherein the shape is centered on a barycenter of said each subspace;
• and
• fifth program instructions to display the data plot with the compressed information representation for said each subspace, wherein each unit of compressed information is displayed on the display adjacent to a corresponding group of data points from the data plot;
• and wherein said first, second, third, fourth, and fifth program instructions are stored on said non-transitory computer readable storage medium for execution by said processor via said computer readable memory.
