I am guessing here as to what you want.

Try this:

psnr_val=[22 24 29 32 33];
exp_t =[0.01 0.1 1 10 100];

figure
semilogx(exp_t, psnr_val)
grid
xlabel('exp\_t')
ylabel('psnr\_val')

Use plot instead of semilogx if you want a linear x-scale.

lokking for answer for a few days Appreciate your help just what I was looking for thanks

and what if I want use vaues of x which are not logarithmic scale is used for t-axis such as exp_t =[0.1 20 150 400 4000]

As always, my pleasure.

If your x values are not logarithmic, use either plot or semilogx, depending on the result you want.

Please feel free to experiment.
