Graph control
Graphs can be controlled and manipulated with the mouse in several ways.
Traces
Traces represent the measured data. Depending on the type of measurement there can be
one or several traces. For parametric sweeps (with more than 1 variable) there will be a
multitude of traces.
The legend at the bottom of the graph indicates the color and type of each trace. With
parametric sweeps the legend will indicate at which parameter value the trace was
measured.
Zoom
To pan and zoom in/out use the arrows at the right / bottom side of the graphs. The number
indicates the zoom factor. The small square at the lower right corner restores the default
value of the scaling. There are controls for the vertical and for the horizontal scale.
Smith charts are always zoomed as a whole, the horizontal and vertical zoom controls
have the same effect.
Cursors and markers
When you move the pointer of the mouse over de graph it will act as a cursor and show
the value at the bottom of the graph. As soon as you move the cursor over a measurement
in a trace the cursor gives you the data of that point.
You can click on a trace to set a marker: There will be a mark on the trace and a value
readout at the top of the graph.
To remove a marker, just click on the marker or on the marker readout.
Markers can only be set on a measurement point. For traces with few measurement points
it can be a little difficult to find the nearest measurement point. The
Show Trace Points
feature can be used to mark each trace point so it can be found easily.
