I have searched the help file, and I can only figure out how to plot a point in the following colors: Red, Green, Blue, Cyan, Magenta, Yellow, Black, and White. I know that you use the command plot(x,y,'g.') to plot a point/points in green, for example. Can anyone tell me how to get orange?

There is no color code for orange. You will have to code it as an RGB
triple.

Thanks for the comment - this has been bugging me too but never quite enough to read through the plotting help files.

So a quick modification of the help example gives orange circles with a black boundary:

plot(somevector,'-ko',...
'LineWidth',1,...
'MarkerEdgeColor','k',...
'MarkerFaceColor',[1 .5 0],...
'MarkerSize',8)

I have tried doing this, but when plotting points, it wont' let me do this. For example, if i try to do the command plot(x,y,'b.') that will plot points in blue. But if i do plot(x,y,'[.5 .5 .5].') it will not work that way. How would i code it in RGB correctly?

No quotes, when giving numerical values.
plot(x,y,'color',[.5 .5 .5]) % plots a grey line.

One thing I did, which you may find useful, is to define color functions. For example, orange.m:


function [C] = orange()
C = [1 .5 0];


Now at the command line:

plot(x,y,'color',orange)

One could define as many such functions as needed.

I figured it out, thanks.

I have found that orange is well described by these two number codes:
[1.0,0.687,0.387]; %light orange
[1.0,0.4,0.0]; %dark orange

Change:
plot(x,y,'[.5 .5 .5].')
To:
plot(x,y,[.5 .5 .5])
