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:

Close.
This button can be used to close the plot window.
(No) Markers.
This button toggles between yes / no markers. See also the join button.
No Join / Join Points.

This button toggles between yes / no connecting the data points with line pieces. Without markers the data points are always connected.
Not available when load data are shown.
This button toggles between the display of all 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.
Time selector
It can be used to control the time domain.
The time selector consists of the attributes with the following titles:
TimeDomain >
With this choice component the time domain TimeDomain can be chosen.

Legends

The legends contains the labels of the net data shown. When there are markers used, they are displayed before the labels. The following actions are bound to the mouse buttons:

Left mouse button released at a legend box.
Do not display the plot trace, represented by this legend, after replotting. 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.
