Meysam Ghahramani thank you for your suggestion , I used (origin) yes of course its easy to using, but its smoothing is not perfect

Safar Saeed Mohammed this is so weird for me, that its smoothing is not perfect. However, one of my friends suggests SigmaPlot, and I found that professionals also use gnuplot. I hope that these will be useful for you.

Meysam Ghahramani thank you, I try to use them

Safar Saeed Mohammed Any program if you're going to apply for smoothing.You have to carefully select the threshold value of smoothing .Otherwise, you get lose information in an image because the contrast of image decease by smoothing.
