Context: 
This option is particularly useful when colors are not available; for
  example, for black and white hard-copy plotting.

You customize the colored lines one color 
  (interval) at a time,
  referring to each interval by its position in the contour legend. Interval
  number 1 is the first colored line starting from the bottom of the contour plot
  legend. For information on the contour legend, see 
  Customizing the legend.
 
  
	 Locate the Line options.
	 
	 
Select
		
		from the main menu bar or click 
		
 in the toolbox. Click the Color & Style
		tab in the dialog box that appears; then click the Line
		tab. The Line options appear.
	 
   
  
	 To choose the interval you want to customize, click the
		Interval arrows until the desired interval number appears
		in the Interval box. 
	 
	 
		
Note:
		
		  
The Style and Thickness
			 buttons change to show the current style and thickness of this interval,
			 respectively. The numbers above and below the Interval box
			 change to correspond to the adjacent interval numbers. The area above and below
			 the Style and Thickness buttons
			 changes to show the style and thickness, respectively, of these adjacent
			 intervals.
		  
		
	 
   
  
	 Choose the style of the interval line:
	 
	 
 
		- 
		  Click the Style button to reveal the style
			 choices.
		  
		
 
 
		- 
		  Click the style you want.

		- 
		  Click the Thickness button to reveal the
			 thickness choices.
		  
		
 
 
		- 
		  Click the thickness you want.

			 Thickness button.
		  
		 
 
	 
   
  
	 Repeat Steps 2 through 4 to customize additional intervals.
	 
  
 
  
	 Click Apply to implement your changes.
	 
	 
The contour lines of the line-type contour plot in the current
		viewport change to reflect your style and thickness specifications. The contour
		legend, if active, will also change to show your selections. For more
		information on the contour legend, see 
		Customizing the legend.
		In addition, tick mark axes, if present, will change to show your selections.
		For more information on tick mark contours, see 
		Contouring line-shaped elements with tick mark contour plots.
	 
	 By default, your changes are saved for the duration of the session
		and will affect all subsequent contour plots. If you want to retain your
		changes for subsequent sessions, save them to a file. For more information, see
		
		Saving customizations for use in subsequent sessions.
