MATLAB: How to create multiple cdfplot in one graph

Question

I have tried to create a multiple cdfplot in one graph as below but I need an efficient way since I'm using this in a big matrix and would you please show how to include the legend as well please.

figure
for ki = 1:size(NPV_all,2)
cdfplot(NPV_all(:,ki)); hold on
end 

Answer 1

figure
hold on
lgd = cell(size(NPV_all,2),1) ; 
for ki = 1:size(NPV_all,2)
    cdfplot(NPV_all(:,ki)); 
    lgd{ki} = strcat('column=',num2str(ki)) ; 
end
legend(lgd)
