I have a function like:

m=zeros(3,4)
for x=1:3
    for y=1:4
        m(x,y)=x*(y+1i*y);
    end
    scatterplot(m(x,:));
    hold on;
end

Although i used "hold on" but Its generating three different plots. Can I plot all three different data in the same plot with different color?

Scatterplot is a really special function that needs a special syntax to plot more that one scatterplot together.

If you need more info I used this, and I add an example of how you can plot some figures together

m =zeros(3,4);
first=1;
for x=1:3
    for y=1:4
        m(x,y)=x*(y+1i*y);
    end
    if first
    h = scatterplot(m(x,:),1,0,'bo');
    first=0;
    else
    h = scatterplot(m(x,:),1,0,'bo',h);
    end
    hold on;
end

The 'bo' param is used to mark the points to be blue('b') circles ('o'). To change the color you can use the normal ones as you do it with plot ('r' = red, 'b' = blue, 'g' = green, 'k' = black...)

m =zeros(3,4);
first=1;
color = ['r','g','b'];
for x=1:3
    for y=1:4
        m(x,y)=x*(y+1i*y);
    end
    if first
    h = scatterplot(m(x,:),1,0,color(x));
    first=0;
    else
    h = scatterplot(m(x,:),1,0,color(x),h);
    end
    hold on;
end
