grabbing values from .txt to create stacked bar graph

report_data.txt contains

I want to grab ( fgetl(fileID) ?) healthy_exposed, pus, and necrotic and create a stacked bar graph.

      figure;
      bar(1:3, cat(1,[healthy_exposed, pus, necrotic]), 0.5, 'stack');

    % Adjust the axis limits
      axis([0 4 0 100]);

    % Add title and axis labels
      title('Chronology of Wound Specifications');
      xlabel('Date of Visit');
      ylabel('Percentage');

      % Add a legend
      legend('Healthy', 'Infection', 'Necrotic');

But I'm not 'grabbing them' properly. How do I do that?

your fgetl(fileID) will get each line of data but you'll have to extract the data from the line. you can use the strfind(line,'=') which will give you your data for each line:

currentline = fgetl(fileID);
equalpos = strfind(currentline,'=');
linesdata = str2num(currentline(equalpos+1:end));

if your reports are consistent you can read in each line and associate the the data to the correct variable. given the specific line you could even use the eval([fgetl(fileID) ';']) such that it'll evaluate the line >>healthy_exposed = 75 ;

Joseph, this is how I grab my values

fileID = fopen('report_data.txt','r');
patientName=fgetl(fileID);
dateOfBirth=fgetl(fileID);
notes=fgetl(fileID);
healthy_exposed = fgetl(fileID);
pus = fgetl(fileID);
necrotic = fgetl(fileID);
ulcer_stage = fgetl(fileID);
area = fgetl(fileID);
volume = fgetl(fileID);
fclose(fileID);

how do I grab them for the stacked bar graph?
