PURPOSE:To attain high speed of a graphic display by using a stored previous plotting command as it is when a display pattern is equal to a previous display pattern and limiting the converting processing of a plotting command of a host processor in a display system consisting of the host processor and a plotting processor to a minimum in the real time display of graphics. CONSTITUTION:Plotting commands subjected to processing such as a coordinate transformation for each display unit data constituting display pattern and supplied to a plotting processor 2 are preserved on the display information data-base 14 in a host processor 1. Then, the high speed processing is attained by sending out a preserved plotting command as it is for display unit data in which a pattern is not changed. For a display unit data in which a display pattern is changed, a display change command 102 is sent to a data management part 12 from an information generating part 11 and then, a plotting command is generated as in a conventional method. |
