    I have problem with applaying the median filter in 3D plot. I have data and among them is a noise. I have to apply on the data filter but gnuplot filters work only on 2D plot, is there any chance to do it in 3D. If you have any experience with this please write it here i would be very thankful.

      gnuplot has neither filters for 3D (other than contouring and dgrid3d, that is), nor does it have any median filter to begin with.

      You'll have to implement those filters yourself, probably as a separate program.  You can do it as an extension to gnuplot, but that'll require extra skills.
