Tag identifier Meaning
CONTROL Continued
● fieldtype
– graphicbox
The field type generates a 2D broken line graphic control. Using the tag <ITEM> a
graphical element can
be inserted into the control. Parameters width and height specify
the width and height of the box.
After the control has been created, additional elements can be inserted using the
functions addItem or insertItem. Parameter itemdata is not evaluated for this control.
If a reference variable is assigned to the control, its values will be recorded in a 100-
ms timebase. Up to 10,000 values can be recorded. With the property max, values are
recorded endlessly. The oldest value is then deleted when the maximum recording
time is reached. The recording time must be specified in milliseconds.
Although the values are stored at discrete times, the control displays them as
connected lines. The attribute channel permits recording of up to three further reference
variables. The index starts with one. Index zero is used to set the properties of the
variables assigned in the control tag.
Example:
<control name= "c_gbox1" xpos = "250" ypos="24" width="240"
height="356" fieldtype="graphicbox" refvar="val" hotlink="true"
COLOR_BK="#ffffff">
<property max="60000" /> <!-- steps of ms -->
<property min="0" />
<property channel="0" color="#00ffff" penwidth="3"/>
<property ORDINATE="Y sinus" />
<property ABSCISSA="time *100 ms" />
<property channel="1" refvar="val2" color="#000000" />
</control>
