VisIt-with-1D-data.md

+VisIt supports visualization of 1D data, however in limited form. For making 1D plots it is suggested to use python w-data library. 
+
+Suppose you have data generated by 1d code for lattice:
+```
+# W-DATA 0.2.0
+# More information about the WData format see: https://gitlab.fizyka.pw.edu.pl/wtools/wdata/-/wikis/home
+nx                      128   # lattice
+ny                       16   # lattice
+nz                       16   # lattice
+dx                        1   # spacing
+dy                        1   # spacing
+dz                        1   # spacing
+datadim                   1   # dimension of block size: 1=nx, 2=nx*ny, 3=nx*ny*nz
+```
+To open it with VisIt, you need to chose `Curve->opretaors->Lineout` plot

+
+and next set `Lineout` attributes, in this case as

+
+To reajust y axis to range of data, you will need `Reset plot` after drawing it:
