Plot Window
Introduction
The plot window shows a two dimensional plot of the current net test table, with
the exception that always the smallest timestep is used. The control about the
data in the plot is handled by the control panel of
the plot window itself. However the most recent
time from the related table is also used
in the plot window. But new loaded net test data are shown in the plot window at
the same time.
Control panel
The plot window can be administered from the control panel which is situated
above the plotted graphics. It contains the following attributes:

join button.

- This button toggles between yes / no connecting the data points with
line pieces. Without markers the data points are always connected.
- Not available when

plot traces, and between the display of the plot traces from the connections
with host Host; these traces represent in fact the same data as
displayed in the
tables.
- Linear / Log
- This button toggles between linear and logarithmic scaling of the
y-axis.

When all legends are shown, see below,
the background of legends, representing no plot traces, is light gray and
the text color of these legends is gray. Please note that the text color of
legends, representing traces is always white or black, depending from the
background of the legend box. When the button is released at a legend, not
representing a plot trace, the corresponding plot trace will be shown after
replotting.

available data are shown in the plot, this flag is set to show the legends
of the not plotted data.
If there are any changes redisplay the plot.
