Book1.xlsx

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.

在 MATLAB Online 中打开

 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'})

thank you for your reply, i tried to use the command but it doesnt work. it said that Undefined function 'histogram' for input arguments of type 'double'. anyway I am using Matlab R2013a version.
