When you start a simulation, Scicos open Scope windows. The Scope
67
block displays its input with respect to simulation time. The Scope
68
block can have multiple axes (one per port); all axes have a common
69
time range with independent y-axes. The Scope allows you to adjust the
70
amount of time and the range of input values displayed.

135
<LI>Output window number: The number of graphic window used for
136
the display. It is often good to use high values to avoid conflict
137
with palettes and Super Block windows. If default value is used <B> (1)</B>, Scicos define the output window number.

140
of the upper left corner of the graphic window. Answer [] for
141
default window position.
143
<LI>Output window sizes:a 2 vector specifying the coordinates of
144
the upper left corner of the graphic window. Answer [] for default
147
<LI>Ymin vector: Minimum values of the input; used to set up the Y-axis
148
of the plot in the graphics window.
150
<LI>Ymax vector: Maximum values of the input; used to set up the Y-axis
151
of the plot in the graphics window.
153
<LI>Refresh period: Maximum value on the X-axis (time). The plot
154
is redrawn when time reaches a multiple of this value.
156
<LI>Buffer size: To improve efficiency it is possible to buffer the
157
input data. The drawing is only done after each <B>Buffer size</B>
