colordg

PURPOSE ^

COLORDG - Provides a choice of 15 colors for a line plot

SYNOPSIS ^

function linecolor = colordg(n);

DESCRIPTION ^

COLORDG - Provides a choice of 15 colors for a line plot
The first seven colors are the same as Matlab's predefined
values for the PLOT command, i.e.

  'b','g','r','c','m','y','k'

Syntax:  linecolor = colordg(n);

Input: N , integer between 1 and 15, giving the following colors

 1 BLUE
 2 GREEN (pale)
 3 RED
 4 CYAN
 5 MAGENTA (pale)
 6 YELLOW (pale)
 7 BLACK
 8 TURQUOISE
 9 GREEN (dark)
 10 YELLOW (dark)  
 11 ORANGE
 12 MAGENTA (dark)
 13 GREY
 14 BROWN (pale)
 15 BROWN (dark)

Output: LINECOLOR  (1 x 3 RGB vector)

Examples:
  1)   h = line(x,y,'Color',colordg(11)); %Picks the orange color
  2)   colordg demo  %Creates a figure displaying the 15 colors
  3)   axes;  set(gca,'ColorOrder',(colordg(1:15)));
       Overrides the default ColorOrder for the current axes only
  4)   figure; set(gcf,'DefaultAxesColorOrder',(colordg(1:15)));
       Overrides the default ColorOrder for all axes of the current
      figure
  5)   set(0,'DefaultAxesColorOrder',(colordg(1:15)));
       Sets the default ColorOrder for all axes to be created during
       the current matlab session. You may wish to insert this
       command into your startup.m file.
