Colors

  

 

 

TRACEc

plt(...,'TRACEc',ct);
Specify trace colors. Usually you will have at least as many rows in ct as there are traces, however if ct doesn't have enough rows, plt will start over from the beginning. For example if you specify:
   TRACEc,[1 0 0; 1 1 0; 1 1 1]
then plt will use red, yellow, and white respectively for traces 1,2, and 3. If you had a fourth trace, plt would use red for that trace and so on. If ct is a single 3 element vector, plt will use that color for all traces. If the TRACEc parameter is not included and color files are not being used (see 'ColorFile' below), then the following default colors are used:

Default (for up to 34 lines): ct =
[ 0  1  0;   1  0  1;   0  1  1;   1  0  0;  .2 .6  1;
  1  1  1;   1 .6 .2;   0  0  1;   1 .2 .6;  .2  1 .6;
 .6  1 .2;  .6 .2  1;   1  1  0;   0 .6  0;  .6  0 .6;
  0 .6 .6;  .6 .6  0;  .7 .7 .7;  .6  0  0;  .2 .2 .7;
 .5 .5 .5;  .7 .2 .2;  .2 .7 .2;   0  0 .6;  .3 .3 .3;
  0 .9 .4;   0 .4 .9;  .9 .4  0;  .4 .9  0;  .9  0 .4;
 .4  0 .9;  .8 .5 .5;  .5 .8 .5;  .5 .5 .8];

If the number of lines (=N) is more than 34, ct is expanded via:
  for k=35:N ct = [ct; .75 * ct(k-34,:)]; end;
This makes each successive group of 34 traces 25% dimmer than the previous group. This creation of default colors continues only up to 99 colors. If you have more than 99 traces, plt will start assigning colors cyclically as described above.

 

CURSORc    

plt(...,'CURSORc',rgb);
Specify the cursor color. Here, and on the rest of this page, rgb must be a 3 element row or column vector.

Defaults: Only one trace
(dark plot backgrounds)		 [1 1 .5]
  Only one trace
(light plot backgrounds)		 [0 0 .5]
  More than one trace Cursor color is set to match trace color

 

DELTAc

plt(...,'DELTAc',rgb);
Specify color indicating the delta cursor.
Default: [1 0 0]

 

PltBKc

plt(...,'PltBKc',rgb);
Specify the plot area background color.
Default: [0 0 0]

 

FigBKc

plt(...,'FigBKc',rgb);
Specify the figure window background color .
Default: [.25 .15 .15]

 

xyAXc

plt(...,'xyAXc',rgb);
Specify the color of the x and y axes.
Default: [1 1 1]

 

xyLBLc   

plt(...,'xyLBLc',rgb);
Specify the color of the x and y axis labels.
Default: [.64 .78 .94]

 

GRIDc

plt(...,'GRIDc',rgb);
Specify the color of the grid lines. Normally the grid lines are drawn in normal erase mode, however if any of the rgb values are negative (e.g. 'GRIDc',[0 -.2 .4] ), then the grids are drawn in exclusive-or mode (which is occasionally preferable). The actual grid color used in the above example is [0 .2 .4]).
Default: [.3 .3 .3]
 

COLORdef

plt(...,'COLORdef',c);
Sets the PltBKc, FigBKc, xyAXc, and xyLBLc colors mentioned above to be consistent with Matlab's current default colors. Trace colors are set as follows:

c = 0 or 'default' Matlab's current default trace colors are used.
i.e.  TRACEc = get(0,'DefaultAxesColorOrder')
c is a 3 column array c is appended to the default trace colors property.
i.e.  TRACEc = [get(0,'DefaultAxesColorOrder') c]
(useful if Matlab doesn't have enough default trace colors)

If TRACEc so defined has fewer rows than the number of traces to be plotted the the colors will be used cyclically as described above.

 

ColorFile

 plt(...,'ColorFile','filename');
The normal behavior of plt (i.e. when the ColorFile argument is not included) is as follows.
  • If plt is called from the MatLab command line, when plt initializes it looks for a file called pltcolor.mat in the folder where you installed plt. If this file isn't found, no action is taken. If it is found, the file is loaded causing all the default colors and the colors specified by all the other parameters shown on this page to be overwritten with the data saved in the .mat file. When you select the "Save figure colors" selection under the Color menu, plt saves the current colors to this same file (pltcolor.mat).
  • If plt is called from a MatLab function or script file, the behavior is similar except that the file name used is fnameColor.mat where fname is the name of the top level MatLab command or script. Again, plt looks for this file in the folder containing the .m file defining fname (or in the folder containing the fname.exe file for compiled applications).

When the 'ColorFile' parameter is included in the plt argument list, the above behavior is modified as follows:

'ColorFile','filename' If the filename is specified without any path, plt uses the specified file name both on startup (to load the color scheme) and when "Save figure colors" is selected. plt looks for this file in the folder containing the .m file defining fname (or in the folder containing the fname.exe file for compiled applications). The extension used is always .mat and you may not include an extension or a period in the filename string.
'ColorFile', 'drive:\path\filename' As above, plt uses the specified file both on startup (to load the color scheme) and when "Save figure colors" is selected. However when path information is supplied, plt will look for the file only in the location given. As before, you may not include an extension in the filename string
'ColorFile','' plt will use its default colors, and any colors specified by the other parameters in this section. A color file will never supersede them on startup, even if fnameColor.mat exists. If you select "Save figure colors", plt will allow you to save the current colors to any file of your choosing (by opening a file selection box), but these colors will not be loaded unless you change to one of the above 'ColorFile' options, or remove the 'ColorFile' parameter altogether.
