Unwanted gap in ListPlot3D [closed]

I tried an answer on the post here and I had an unwanted gap (see attached picture)

Does anyone know how to avoid this gap?

• try removing the option PlotRange from the definition of pltstyl (or change it to PlotRange -> All)

• Thanks, It worked. I changed the limits of PlotRange to ->All. Sep 8, 2021 at 10:10
• Should I post a code for the solution? Sep 8, 2021 at 10:13
• Thapanio, that's a good idea.
