3.5.8  Configuring the graphics

You can configure each graphics screen by clicking on the cfg button on the graphics screen’s control panel to the right of the graph. You can also change the default graphical configuration using the the menu item Cfg▸Graph configuration. You will then be given a window in which you can change the following options:

• X- and X+
  These determine the x values for which calculations will be done.
• Y- and Y+
  These determine the y values for which calculations will be done.
• Z- and Z+
  These determine the z values for which calculations will be done.
• t- and t+
  These determine the t values for which calculations will be done; when plotting parametric curves, for example.
• WX- and WX+
  These determine the range of x values for the viewing window.
• WY- and WY+
  These determine the range of y values for the viewing window.
• TX and TY
  These determine the tick ranges on the x- and y-axes.
• class_min
  This determines the minimum size of a statistics class.
• class_size
  This determines the default size of a statistics class.
• autoscale
  When checked, the graphic will be autoscaled.
• ortho
  When checked, all axes of the graphic will be scaled equally.
• >W and W>
  These are convenient shortcuts to copy the X-, X+, Y- and Y+ values to WX-, WX+, WY- and WY+, or the other way around.

Note that the viewing window is not the same as the calculation window; if the calculation window is larger than the visible window, then you can scroll to bring other parts of the calculation window into view.

This page also has buttons for applying the settings, saving the settings for future sessions, or canceling any new settings.
