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(:));

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
