Graphic objects that represent the course of a process are called by symbolic names by an application programme (AP) from a programming and displaying system (XM). Programming is carried out by means of an editor (XME). The graphic object that represents a measurement value is defined as a dynamic measurement object. When all required parameters are input, a measurement value table is coupled to the measurement object. The programme library of the programming and displaying system (XM) is linked to the application programme (AP) after translation. While the application programme (AP) is executed, a new measurement value is represented by a call by programming means of the programming and displaying system (XM). These means calculate the new dimensions, the new position, the new attributes, erase the measurement object at its previous location and draw the new one. |
