How do I use the values in a .txt file to create a stacked bar graph?
显示 更早的评论
I've already been successful at opening the file and obtaining the 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);
But I'd like to take healthy_exposed, pus, and necrotic and create a stacked bar graph.

bar( [str2num(healthy_exposed)', str2num(pus)', str2num(necrotic)'], 'stacked')

You must convert your data to numeric type first. fgetl returns charactor type. Use str2num to convert it to numeric type. You might be getting this error because of strings of unequal length.

Hey Dishant, I did recently use str2num actually.
figure;
bar(cat(1, str2num(healthy_exposed), str2num(pus), str2num(necrotic)), 'stacked');
The result is this. It failed to produce a 'stacked' bar graph.

I was wrong on my part. I have made appropriate changes in the answer.
