I have a loop that do a function forteen times.Each time it averages some values and makes a plot.It means there are are fourteen plots at on one graph.I am having problem with the colors of these plots.I want to give each plot a black color line with some squares,or cross,or diamonds etc.I made a new vector cotaining all the names of the color and each time it should select one of the color.Some of my code is shown below

colors=['k+:','k.-','kx-','k+-','k*-','ks-','kd-','kv-','k^-','k<-','k>-','kp-','kh-','k--'];
for k=1:1:length(BigMa_1); # Length of BigMa_1 is 14 
code 
plot(vector./100,yi,colors(k),'DisplayName',['Step No',' ',num2str(k)],'LineWidth',1);
end 

Problem is it does not display the black lines.It shows some weird shapes.I am stuck here for two months.Can any one help me in this regard.I need to produces black line with different symbols like plus,square,star ets data poinst

在 MATLAB Online 中打开

colors = {'k+:','k.-','kx-','k+-','k*-','ks-','kd-','kv-','k^-','k<-','k>-','kp-','kh-','k--'};
for k=1:1:length(BigMa_1); % Length of BigMa_1 is 14 
    code 
    plot(vector./100,yi,colors{k},'DisplayName',['Step No',' ',num2str(k)],'LineWidth',1);
end
