Commands and zoom functionality
For "working" in the Trace Editor in offline resp. in online mode there are commands
available in the Trace menu as well as in the trace window. The Trace menu provides
commands for operating the trace graph. With focus on the diagram in the trace
window the context menu provides the trace menu commands too. The trace
configuration with trigger setting and the variable selection can only be done in the
context menu of the right part of the trace window where the trace tree is visualized.
Up to the selection in the trace tree different commands are enabled.
Notice that besides the zoom commands also a "scroll mouse" can be used to zoom the
display of the coordinate system in the trace window.
Configuration of the trace
A "Trace" object can be added in the Devices view window by the 'Add Object'
command and by 'Edit Object'. Primarily the main editor window, titled with "
<name of trace object>", shows an empty area in the left part where later the trace
graph will be displayed and the trace tree as configured in the Configuration... dialog in
the right part.
Abb. 427 Trace editor window, no configuration
A trace defines one or several variables to be traced. For this common settings can be
defined concerning the start of the trace, sampling, trigger conditions, buffer size,
responsible task etc.. Beside that the "appearance" (display parameters for the
coordinate system where the curve will be displayed) of every trace variable has to be
set.
