I trying to scatterplot multiple data plots but cannot seem to do it correctly.
I tried
scatterplot(data1);
hold on
scatterplot(data2);
I just receive 2 figures with each separate scatterplot.. How do i put into one.. I have to merge 94 dataset into one scatterplot.. So...

Try scatter() instead:
scatter(data1(:, 1), data1(:, 2));
hold on
scatter(data2(:, 1), data2(:, 2));

That seem to work.. Do have any idea on how to not manually plot each individual dataset?

What's wrong with the code? How is this "manual" and not "automatic"? scatter() does nearly all the work (all you have to do is to simply call it) - isn't that "automatic"? And what difference does it make as long as it does the job?

h = scatterplot(data1);
hold on
scatterplot(data2, h);
You might need to provide all of the arguments for the second call to scatterplot(); see the documentation page.
