The title of a plot containing the data's file name.

I have a program that allows the user to select a set of data in a txt file. This data is then plotted. I was wondering as to how I can get the name of the data file to appear in the title of that plot. 
[filename]=uigetfile('*.txt')

%Loading the data the user has selected.
Data=load(filename);

%read file and make 3 colunm vectors
Easting_Data=Data(:,1);
Northing_Data=Data(:,2);
Depth_Data=Data(:,3);


%plotting the original unfiltered data for the user to view.
plot3(Easting_Data,Northing_Data,Depth_Data,'.')
view(2)
%HOW CAN I GET FILENAME TO APPEAR BELOW AFTER THE STATEMENT
title('UTM Position of the data in file')

You have filename already when you load the data. Just need to combine this with the char array you have. Try

title(['UTM Position of the data in file ' filename]);
