Title
Across the top of the diagram area, an optional title describes the contents of the area. Different areas
within a setup are distinguished by area numbers in the upper right corner.
Use the context menu or the functions in the Display menu to display, hide or change the title and
to add and customize diagram areas.
Traces
A trace is a set of data points displayed together in the diagram area. The individual data points are
connected so that each trace forms a continuous line.
The trace can be complemented by the following display elements, plotted with the same color:
• Reference value (for all traces): The Reference Value is indicated with a triangle
at the right
edge of the diagram and a dashed, horizontal line. The value and position of the triangle can be
changed in order to modify the diagram scale and shift the trace vertically.
• Measured quantity (for the active trace): The measured quantity is indicated in the left upper
corner of the diagram.
A trace can be either a data trace, a memory trace, or a mathematical trace; see Trace Types below.
Context menu of the diagram area
A right mouse click on any point of the diagram area (except the marker info field and the measured
quantity info) opens a context menu:
The settings correspond to the most common commands in the Display – Area Select and Display –
Config View menus.
Trace Types
The analyzer uses traces to display the current measurement result in a diagram area but is also
capable of storing traces to the memory, recalling stored traces, and defining mathematical relations
between different traces. There are three basic trace types:
