Hey Guys, I want to give the User of my PlotingProgram the option to choose the color of the plot lines. I would be really happy about some ideas or tips.
My current Thought is:
-Creating a pie plot
-using different coulors for each segment of the plot
-the user click in one segment of the plot
-regarding to the Coordinates of the click the program selects the coulor

What have you attempted? This is a quite long request. You will need to create a gui for this. Check out guide and/or callback functions.
This is something I put together fast some time ago:
function myCallback(hObject,eventdata)
c = 'krym';
n = randi([1,4],1);
ch = get(gca,'Children');
set(ch,'Color',c(n));
Apply this callback some standard plot like plot(1:10,'LineW',2,'ButtonDownFcn',@myCallback);. The function randomly selects a color from c. This could work as inspiration.

Max - could you perhaps include a description of the solution/answer so that others (when viewing your posted question) can get an idea of how you went about solving this problem?

Hi Max,
Sorry I'm a bit lazy to actually write a code, but I'm sure you can do it, and you can do it the you want it.
I read your question and they way I would do this is to use
[x,y] = ginput(n)
to let the user click on n segments, or you may do it one by one, then I would normalize the x and y values in respect to their max and min allowed values, so x and y end up being between 0 and 1, and I would use normalized x and y for a new color, [x y 1]
So you would never end up having the same color.
