Apparatus for storing and displaying graphs

A graph generating device which displays a graph on a display unit having a means for changing the layout of the graph, said graph having a plurality of graph elements, said device comprising:

• memory means for storing display position data and display size data corresponding to numerical data for each said graph elements constituting a graph, the numerical data, graph layout data, and the display position and display size data stored in the memory means being arranged to correspond to each other;
• display control means for controlling the display unit to display the graph elements on the display unit based on the data stored in the memory means;
• position directing means for directing a new display position of a graph element displayed on the display unit;
• position update control means for updating display position data stored in the memory means based on the display position directed by the position directing means;
• and
• size directing means for directing new numerical data to change numerical data corresponding to at least one of the graph elements.
