Channel Graph Frame
A Channel Graph frame provides a graphical look into the database it is attached
to. The database is attached to the Trend Graph frame when it is created. This
can be done manually by placing a graph frame or automatically when using a
template.
The graph frame provides additional tools for viewing the underlying database.
These tools provide zoom and pan operations. In addition, individual traces and
waveform snapshots can be selected using the Select Frame tool.
Normally, the Select Frame tool is used to select a frame for modification. In
addition to selecting the Graph frame, this tool is used to select individual traces.
A trace is selected if any part of it is drawn within a few screen pixels of where
the selection tool is when the left mouse button is pressed.
When a trace is selected, handles similar to those of the frame handles are
drawn over the trace. If more than one trace is drawn within the proximity of the
selection tool, when clicked again, the next trace will be selected. This will
continue until all traces within the selection tools proximity have been selected.
