how to draw bar plot for histogram values?
显示 更早的评论
I have computed the precision,recall and f measure for the algorithm. I want to draw bar plot for the three values. Precision=1*256,recall=1*256,F-measure=1*256. I am getting figure like this.
But, I want something like this and I have attached the text file
I have written the code
data = [P_1,R_1,f_1,
P_2,R_2,f_2,
P_3,R_3,f_3
P_4,R_4,f_4];
b=bar(data);
set(b(1),'FaceColor','b');
set(b(2),'FaceColor','r');
set(b(3),'FaceColor','y');
grid on;
set(gca,'XTickLabel',{'DEMO1','DEMO2','DEMO3','DEMO4'});
legend('Precision','Recall','F_\beta');

Can you post your underlying data (P1, etc.), or a small sample that exhibits the problem?

It would be a lot more convenient if you uploaded a MAT file with the variables already uploaded and formatted.

Here you go.
Can you do the same for your other variables?

I stupidly overlooked a very basic problem with what you are doing.
Your data matrix has 12*256 = 3,072 values. But the bar chart you want only plots 18 values.
What is it that you actually want to plot?

My guess is that you are grouping the wrong dimension. Try using the transpose
bar(data')

Thank you for your answer. But it is not working
