lmt_chart_bar with data from luacode

Dear Sirs

If I tried:

\starttext
\startluacode
sample = {10,30,30,40}

 function MP.GetP()
 mp.print(sample)
 end
\stopluacode

\startMPcode
draw lmt_chart_bar [
 width = 8cm,
 height = 10mm,
 samples = {lua.MP.GetP()} ,
 trace = true,
 maximum = 100,
 linewidth = 1mm,
 showlabels = false,
 originsize = 0,
 labelanchor = "lft",
 labelcolor = "black"
 labelstyle = "bfxx"
 legendstyle = "tfxx",
 labelstrut = "yes",
] ;
\stopMPcode

\stoptext

This works.

But with an extra element in the sample table:

\starttext
\startluacode
sample = {10,30,30,40,50}

 function MP.GetP()
 mp.print(sample)
 end
\stopluacode

\startMPcode
draw lmt_chart_bar [
 width = 8cm,
 height = 10mm,
 samples = {lua.MP.GetP()} ,
 trace = true,
 maximum = 100,
 linewidth = 1mm,
 showlabels = false,
 originsize = 0,
 labelanchor = "lft",
 labelcolor = "black"
 labelstyle = "bfxx"
 legendstyle = "tfxx",
 labelstrut = "yes",
] ;
\stopMPcode

\stoptext

Don't works anymore. Why?

Thanks for your time and support.

(watch out: samples is global in your code)

your lua.MP.GetP() becomes some mp quantity and 4 entries becomes a 
cmykcolor and you're just lucky that that works (reverse casting makes 
it a table) and there is no 5 element quantity so, you end up in 
scantokens not being able to understand it

I'll think of a way to pass records (new submechanism) at some point but 
for now i added this:

\startluacode
     document.samples = {
         { 10, 30, 30, 40, 50 }
     }
\stopluacode

\startMPcode

draw lmt_chart_bar [
  width = 8cm,
  height = 10mm,
  trace = true,
  maximum = 100,
  linewidth = 1mm,
  showlabels = false,
  sampleset = "document.samples",
  originsize = 0,
  labelanchor = "lft",
  labelcolor = "black"
  labelstyle = "bfxx"
  legendstyle = "tfxx",
  labelstrut = "yes",
] ;
\stopMPcode

with the spec being some lua, so this will also work:

  sampleset = "table.load('foo.lua')",

asuming foo.lua has this:

return {
     { 10, 30, 30, 40, 50 }
}

Dear Hans

I tried this code, but it didn't work. This is not my day.


%%%%%%%%%%%%%%%
\starttext

\startluacode
 document.samples = {
 { 10, 30, 30, 40, 50 }
 }

 function document.dados()
 return { { 10, 30, 30, 40, 50 }}
 end
\stopluacode

\startMPcode
 draw lmt_chart_bar [
 samples = "table.load('document.dados')",
 percentage = true,
 cumulative = true,
 showlabels = false,
 backgroundcolor = "lightgray",
 ] ;
\stopMPcode

\startMPcode

draw lmt_chart_bar [
 width = 8cm,
 height = 10mm,
 trace = true,
 maximum = 100,
 linewidth = 1mm,
 showlabels = false,
 samples = "document.samples",
 originsize = 0,
 labelanchor = "lft",
 labelcolor = "black"
 labelstyle = "bfxx"
 legendstyle = "tfxx",
 labelstrut = "yes",

Using the latest version made it work here.
