20.6.24 Histogram
A histogram element can be used to visualize an array. The values of the array
elements will be represented by bars or lines side by side, indicating the current values
of the element by their height.
Dialog for the configuration of a Histogram
The configuration dialog will be opened as soon as you insert a histogram element
into a visualization object. A Preview is part of the dialog, immediately showing how
the element will look as a result of the currently set parameters:
Presentation: Activate one of the options Barchart or Lines.
Show horizontal lines: If this option is activated, horizontal lines spanning the
diagram will additionally display the scale gradation.
No Scaling: If this option is activated, the inserted element cannot get resized.
Alarm color: This button opens the dialog Configure alarm, where you define at which
value the bar will be displayed in alarm color and which is the alarm color: Insert the
desired threshold value in the edit field and activate one of the Conditions greater
than or less than, in order to define whether values higher or lower than the limit
value should set off an alarm. Press button Alarm color to open the standard dialog or
a target-specific color selection list for choosing the alarm color. Close both dialogs
with OK in order to confirm the settings and to return to the main dialog for
configuring the histogram.
