How to use scatterplot in a loop

Hi all,

I have two data sets which are matrixes 100x18 double.

I want to scatterplot:

column 1(data1) vs column 1 (data2)

column 2(data1) vs column 2 (data2)

....

column 18 (data 1) vs column 18(data2)

The below:

for g=1:length(Data2) %for each column
    
    scatter(Data1(g), Data2(g));
end

produces:

I would like these data sets plotted in diffrent colours. Can you help please?

Try this:

clear;clc;
Data1 = reshape(1:100*18,[],18);
Data2 = randi([50 100],100,18);
c = repmat(linspace(1,10,18),100,1);
scatter(Data1(:),Data2(:),[],c(:));

@Simon Chan Thanks!

So the below produces what I want but cant get the two data sets in diffrent colours:

for k=1:size(Data1,2)
% for k=1
    c = repmat(linspace(1,10,18),100,1);
    figure(k)
    scatter(Data1(:,k),Data2(:,k),[],c(:,k))
end

Do you want two colors or 18 different colors?

[Tomaszzz]

two

If everything plot into one figure, see below:

Or do you want to plot them in separate figures?

Data1 = randi([1 50],100,18);               % Value for dummy data from 1 to 50 (Set #1)
Data2 = randi([50 100],100,18);             % Value for dummy data from 50 to 100 (Set #2)
scatter(1:1800,Data1(:),[],[1 0 0]);        % 1st set
hold on
scatter(1:1800,Data2(:),[],[0 1 0]);        % 2nd set
hold off

Thanks @Simon Chan your first answer is what actually wanted
