Adding new lines to a plot using a for loop

I need to plot a graph with 5 lines from data in a for loop that changes with every loop ie an additional line must be plotted on the same figure for each time the loop is completed.

for i = 1:5
    newmatrix = i * othermatrix + originalmatrixx;
    figure
    ksdensity(newmatrix(:,30))
end

Please do use "hold on" within loop.

figure,
for i = 1:5
    newmatrix = i * othermatrix + originalmatrixx;
    [var1 var2]=ksdensity(newmatrix(:,30))
    plot(??)  %plot parameters 
    hold on;
end
