What have you tried? Do you have any attempts?

I tried with hist plot it didnt workout. I need to plot different type of PDF(weibull, log normal, Rayleigh etc.) for an sonar texture image.

You have to use plot function

Answer 1

[KALYAN ACHARJYA]

gray_image=rgb2gray(imread('image_test.jpg'));
[r c]=size(gray_image);
pix_prob_normal=imhist(gray_image)./(r*c); 
plot(0:255,pix_prob_normal);
xlabel('Gray Levels');
ylabel('Pixels Probability');

I need to plot different type of PDF(weibull, log normal, Rayleigh etc.) for an sonar texture image

pix_prob_weibull=
plot(.....)
hold on;

so on...

At last use Legends

Hope you can do the other plots.
