Description

At the start of a simulation, Scicos opens Scope windows. The Scope block displays its input as a function of the simulation time. The Scope block can have multiple axes (one per port); all axes have a common time axis with independent y-axes. The Scope allows you to adjust the amount of time and the range of input values displayed.

Dialog box

• Input ports sizes
  It allows multiple input ports.
  Properties : Type 'vec' of size -1

• Drawing colors
  a vector of integers. The i-th element is the color number (greater than 0) or dash type (less than 0) used to draw the evolution of the i-th input port signal. See plot2d for color (dash type) definitions.
  Properties : Type 'vec' of size -1

• Output window number
  The number of graphic window used for the display. It is often good to use high values to avoid conflict with palettes and Super Block windows. If default value is used (1), Scicos define the output window number.
  Properties : Type 'vec' of size 1

• Output window position
  a 2 vector specifying the coordinates of the upper left corner of the graphic window. Answer [] for default window position.
  Properties : Type 'vec' of size -1

• Output window sizes
  a 2 vector specifying the coordinates of the upper left corner of the graphic window. Answer [] for default window position.
  Properties : Type 'vec' of size size -1

• Ymin vector
  Minimum values of the input; used to set up the Y-axis of the plot in the graphics window.
  Properties : Type 'vec' of size size(%1,'*')

• Ymax vector
  Maximum values of the input; used to set up the Y-axis of the plot in the graphics window.
  Properties : Type 'vec' of size size(%1,'*')

• Refresh period
  Maximum value on the X-axis (time). The plot is redrawn when time reaches a multiple of this value.
  Properties : Type 'vec' of size size(%1,'*')

• Buffer size
  To improve efficiency it is possible to buffer the input data. The drawing is only done after each Buffer size call to the block.
  Properties : Type 'vec' of size 1

• Accept herited events 0/1
  if 0 CSCOPE_f draws a new point only when an event occurs on its event input port. if 1 CSCOPE_f draws a new point when an event occurs on its event input port and when it's regular input changes due to an event on an other upstrem block (herited events).
  Properties : Type 'vec' of size 1

• Name of Scope
  Name/label of the block.
  Properties : Type 'str' of size 1
