Chart module

Chart module

[Aditya Mahajan]

Hi,

Nested flow charts do not work in the current chart module.

\usemodule[chart]
\startFLOWchart[A]
   \startFLOWcell
     \name{A}
     \location{1,1}
     \text{A}
   \stopFLOWcell
\stopFLOWchart

\startFLOWchart[B]
   \includeFLOWchart[A][x=1,y=1]
\stopFLOWchart

\startFLOWchart[C]
   \includeFLOWchart[B][x=1,y=1]
\stopFLOWchart

\starttext
\FLOWchart[A]

\FLOWchart[B]

\FLOWchart[C]
\stoptext

gives

! LuaTeX error 
...-minimals/texmf-context/tex/context/base/m-chart.lua:563: attempt to

quick fix, line 324:

     for i=1,#subdata do
         local si = subdata[i]
         if si.include then
             inject(si,data,hash)
         else
             local t = {
                 x        = si.x + xoffset,
                 y        = si.y + yoffset,
                 settings = settings,
             }
             setmetatableindex(t,si)
             data[#data+1] = t
             hash[si.name or #data] = t
         end
     end
