<p>PURPOSE:To plot interruptive plotting vector data in a short time and to plot even data with low priority by providing a specific schedule mechanism. CONSTITUTION:This device is provided additionally with a plotting indication processing part 3, a plotting indication storage part 5, a plotting schedule processing part 7 which makes a schedule changing with time according to a plotting indication including priority where a time function is added, and a plotting raster data storage part 10. For example, a plotting indication time is set to 11:45, 29th, Aug. 1988 and priority levels 1, 2, and 3 are so set that plotting is enabled 1, 4, and 24 hours later; when this indication is inputted to the processing part 3, the processing part 3 converts the plotting indication according to the specified time and priority and stores the result in the storage part 5.</p> |
