Color Scale for looping script
显示 更早的评论
Hello everyone,
I have some excel files. Each file containing some columns of parameter. I want to plot all of them in one graph with different color gradation (let's say jet colormap).
Below is my existing code from the begining but it failed to plot what I want (I don't know why, this code only plots one file/profile). Does Anyone know the lines I should modify?
best regards,
A=dir('*.xlsx'); %xls
for nn = 1:length(A)
filename = A(nn).name;
data = xlsread(filename); %
z = data(:,1); %first column
s = data(:,2);
t = data(:,3);
numprof = length(A); %number of profile
couleur = jet(numprof);
for nprf= 1:numprof
plot(s,t,'LineWidth',1,'color',couleur(nprf,:));
%legend of plot (?)
end
end

Add
hold on;
after first line.

"I want to plot all of them in one graph with different color gradation (let's say jet colormap)."
You are plotting lines, which only have a single color assigned/attributed to them.

I want something like this.... this plot is using jet as the colormap. I don't think it should be scatter or surface to get.

Okay, you mean different colors for different plots. See my answer below.

There is no need of the 2nd for loop, remove it. I have taken random data for example to show a working code below.
A=dir('*.xlsx'); %xls
%% Random value
numprof = 10; %length(A); %number of profile
couleur = jet(numprof);
%% Call a figure
figure
%% hold on to retain plots on the same figure
hold on
for nn = 1:numprof
%filename = A(nn).name;
%data = xlsread(filename); %
%z = data(:,1); %first column
%% Random data for example
s = rand(1,6);
t = rand(1,6);
plot(s,t,'LineWidth',1,'color',couleur(nn,:));
end
hold off
legend(compose("%d", 1:numprof))
