The present invention provides a structural graph display system which makes use of central region distribution of graphic parameters to make index tables to reduce the bit number required for storing each graphic parameter. Each structural graph is formed by at least one sub-graph, and each sub-graph comprises a plurality of parameters which includes a target parameter array. The system further comprises an index table which comprises a set of reference parameter arrays. Each reference parameter array has a corresponding reference index number. The index table further has at least one special index number. Within the graphic description file, each sub-graph of a structural graph has a replacement ID for replacing the target parameter array; if the offset between the target parameter array and any reference parameter array is within a predetermining offset range, the replacement ID is formed by the reference index number of the reference parameter array and a offset array. If not, the replacement ID is formed by the special index number and the target parameter array.
