You can use plot or scatter for 2D comparison.If you want a 3D comparison, you can use surf for that. MATLAB has a lot of visualizaton tools and techniques. Please elaborate on what kind of visualization you want.

I assume you have 4 columns:
name = data(:,1);
DOB = data(:,2);
Date = data(:,3);
Time = data(:,4);
% Now create a sub-matrix that contains information for people who have policy time< 12
logicalmatrix = data(:,4)<12 % this will return logical values (1 or 0) for all the values smaller then 12 pm in column 4
data1=data(:,:).*logicalMatrix; % this will put all the non-required values as 0;
data1( ~any(data1~=0,2), : ) = []; %this will remove all the rows that contain non-required values
plot(data1); %or whichever columns you want to plot
Hope that helps!
