Prompt User Input for a Graph

Hi all.

I am struggling with a Lab assignment that requires you to prompt for user input to create the graph itself.

clear
clc
clf

oneLine = ' ';
i=1;

numVal = [2006 95 30 42 149

2007 109 33 43 164

2008 95 33 36 167

2009 95 42 39 209

2010 117 35 33 176

2011 114 29 39 147

2012 120 22 40 110

2013 126 30 44 151

2014 120 33 43 166

2016 109 47 41 236];

%Open comma-separated file
fh = fopen('Cholesterol.csv', 'r');

%Read in one line at a time and build the numVal array
while ~feof(fh)
    oneLine = fgetl(fh);
    token  = textscan(oneLine,'%d','delimiter', ',');
    numVal = [numVal token{i}];  
end
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

%Define length of x - look at the data file (how many points on each line)
%
%Add title
%
%Prompt for the four line colors and styles
%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

set(gca,'XTick',1:length(numVal));
set(gca,'XTickLabel',numVal(1,:));

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

%On SAME graph, plot Triglycerides, HDL Cholesterol,
%VLDL Cholesterol, and LDL Cholesterol
%Use both the line color and style as entered by user),
%Use marker style according to lab instructions
%Marker face colors must be filled in and the same as the line color
%
%Add a legend in upperright corner

This is the code we must edit, provided by the instructor.

How would I implement these user prompts into the code above? Thanks

Ashwin - consider using fprintf to write out some text (to the user) and then input to get their response.

I am able to create the prompt, but it is the process after that that I don't know what to do. For ex, making it iterative so that after the final prompt it results in the graph being displayed.

types = {'LDL', 'VLDL', 'HDL'};
for ind = 1 : length(types)
    this_type = types{ind};
    fprintf('For %s Cholesterol choose one of the following':, this_type);
    fprintf('g ground\nr radiccio\nc celery\n');
    letter{ind} = input(' ', 's');
end
