the RCS and cartesian plot representations

• Click on ``cartesian plot'' or ``RCS cartesian plot''. A working window appears (see figure 1.5) representing by default the first value plotted.
  Each component of this working window is described below.

  Figure 1.5: 1D working window: cartesian plot.

  

• The toggles ``x axe'' and ``y axe'' represent the axis, while ``RCS is the plotted value.
• To modify the range on the x- y- axis, modify the ``x-, y-range'' values. Then click on ``redraw'' to validate the new values.
• To modify the first x-, y- axis mark and the increment between each plotted mark, modify the ``x-, y- tics'' values. , then ``redraw''.
• To go back to the default ranges and increments, click on ``reset''
• To change visualizated value, click on ``Value'' . A selection box appears (see figure 1.6), highlight a value to draw its representation.

• Click on ``point'' in the working window (a window appears and gives informations about points, see figure 1.7).

• If you want to know the coordinates of a point, keep the central mouse button pressed (in the drawing area) and look at the varying coordinates values when moving the mouse.
• If you want to know the value of the selected variable at an x coordinate, click the left button mouse on the drawing area and look at the named value (rcs in this example) on the point window.
• You can click on ``BigView'' to have a big drawing area.
• You can quit the working window by clicking on ``Cancel'' .
