How to make separate graph for each class?

Hello, i have 6 classes in my project and i need to make one graph for each class... now my graph looks like this and i need graphs with average precision for each class...

...

i want each graph to look like this :

Hard to know how to answer this without having your data and code.

[Adrian Kleffler]

should i put my entire code here ?

At least the data and code you used to create your two figures. We need something to work with.

Only the first figure is mine, second one is just screenshoted from matlab page.

i have this code :

Run the detector on all the test images.

detectionResults = detect(detector,testData);

Evaluate the object detector using average precision metric.

[ap,recall,precision] = evaluateDetectionPrecision(detectionResults,testData);

Plot the PR curve.

recallv = cell2mat(recall);
precisionv = cell2mat(precision);
[r,index] = sort(recallv);
p = precisionv(index);
figure
plot(r,p)
xlabel("Recall")
ylabel("Precision")
grid on
title(sprintf("Average Precision = %.2f",ap))

----------------------------------------------------------

Here are the data

recall :

[0;0.166666666666667;0.333333333333333;0.500000000000000;0.666666666666667]

17x1 double

[0;0;0;0;0;0]

15x1 double

[0;0.111111111111111;0.222222222222222;0.333333333333333;0.444444444444444;0.555555555555556;0.666666666666667;0.777777777777778]

precision:

[1;1;1;1;1]

17x1 double

[1;0;0;0;0;0]

15x1 double

[1;1;1;1;1;1;1;1]

----------------------------------

i hope this will help you with helping me :)

After adding numbers for example 1 to "ap" the figure looks like this (but i don´t know if it´s figure only for first class or no) :

recallv = cell2mat(recall);
precisionv = cell2mat(precision);
[r,index] = sort(recallv);
p = precisionv(index);
figure
plot(r,p)
xlabel("Recall")
ylabel("Precision")
grid on
title(sprintf("Average Precision = %.2f",ap(1)))

Your data does not appear to have copied correctly. Try saving your variables to a mat file and then attach that to your post using the paperclip icon.

To make separate graphs for each class in MATLAB, you can follow these general steps:

1) Identify the classes in your dataset. Depending on your data format, you may need to extract the class labels from your data.

2)Iterate over the classes and create separate graphs for each class. Within each iteration, filter the data points based on the current class and plot them.
