LBL Socio-Economic Environmental-Demographic Information System (SEEDIS). Chart:Graphic Analysis and Display System.

摘要

The Chart Graphic Analysis and Display System was developed as part of Lawrence Berkeley Laboratory's Socio-Economic-Environmental-Demographic Information System (SEEDIS) to provide a tool with which users could draw graphs,print tables of numbers,do analysis,and perform basic statistical operations on the same set of data from a terminal in their own office. The Chart system's operation is completely independent of the type of data being entered and has been used for applications ranging from employment to energy data. Users frequently save the data they put into Chart and add to it on a regular basis,and thereby create personal databases which can be blended with information from the formal databases maintained at LBL. Using any computer system requires that the user learn a set of instructions,which at the onset often seems overwhelming. It is the purpose of this workbook to make this initial learning process less traumatic. The typical use of Chart is to enter a set of numbers,and then tell Chart what should be done with them. Chart commands take the form of gruff pidgin English. There are approximately 50commands available. This workbook illustrates the basic commands. (ERA citation 04:011972)
