Plotting bar graph using loop
显示 更早的评论
Hi, may I know how to plot bar graph that can show how many people are in the range of 0.00 to 0.30 and how many people are within range 0.30 to 0.50 and those exceeding 0.50. I tried using these commands but it does not work.
filename=('Book 1'); A=xlsread(filename,'Sheet 1'); A(isnan(A))=0; y1=(A(1:8,2)); % x axis position y2=(A(1:8,3)); % y axis position y3=(A(1:8,4)); % z axis position binranges=[0:0.30,0.30:0.50,0.50:0.60]; [bincounts,ind]=histc(y1,binranges); bar(binranges,bincounts,0.8,'histc'); hold on; [bincounts,ind]=histc(y2,binranges); bar(binranges,bincounts,0.8,'histc'); hold on; [bincounts,ind]=histc(y3,binranges); bar(binranges,bincounts,0.8,'histc'); xlabel('Position (cm)','FontSize',20); ylabel('Number of people','FontSize',20); title('Pass Rate Report for IMRT Verification','FontSize',20); set(gca,'FontSize',20);
Attached is the file for the data

I think this is the same question as this one: Problem with loop to construct graph Please check to see if the answer provided satisfies your inquiry.
Also, it's good practice to bump old questions instead of asking new ones, since it increases the total number of views/reach and avoids redundancy. Cheers.

A=xlsread(filename);
for i = 1:3, h = histogram(A(:,i+1), [0 0.3 0.5 Inf]); hi(i,:) = h.Values; end
bar(hi)
legend({'0:0.3', '0.3:0.5', '0.3:1'})

Then you can use
for i = 1:3, hi(i,:) = histcounts(A(:,i+1), [0 0.3 0.5 Inf]); end
