Description

This block realizes the visualization of the evolution of the three regular input signals by drawing the third input as a function of the two others at instants of events on the event input port. When a point is drawn on screen it stays until the buffer length is reached. This scope is useful to make simple animations.

Dialog box

• Number of Curves
  Set the number of curves.
  Properties : Type 'vec' of size -1

• color
  an integer. It is the color number (greater than or equal 0) or marker type (less than 0) used to draw the evolution of the input port signal. See xset() for color (dash type) definitions.
  Properties : Type 'vec' of size -1

• line or mark size
  an integer.
  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 you have more than one scope, make sure they don't have the same window numbers (unless superposition of the curves is desired).
  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 width and height of the graphic window. Answer [] for default window dimensions.
  Properties : Type 'vec' of size -1

• Xmin and Xmax
  Minimum and Maximum values of the first input; used to set up the X-axis of the plot in the graphics window.
  Properties : Type 'vec' of size -1

• Ymin and Ymax
  Minimum and Maximum values of the second input; used to set up the Y-axis of the plot in the graphics window.
  Properties : Type 'vec' of size -1

• Zmin and Zmax
  Minimum and Maximum values of the third input; used to set up the Z-axis of the plot in the graphics window.
  Properties : Type 'vec' of size -1

• Alpha and Theta
  Set Alpha and Theta for the 3D view.
  Properties : Type 'vec' of size -1

• Buffer size
  An integer value. In order to minimize the number of graphics outputs, data may buffered.
  Properties : Type 'vec' of size 1
