Text in a plot

[davidvincentjones]

Just to confirm:

Applying text within a plot routine has a problem
        pd 'text 0  -20x test      1      2     3'

prints/displays as
        text1 2 3

This makes it difficult to add a table into any plot.

Are you looking for something like

   pd 'text 0  -20x test . . 1 . . 2 . . 3'

?

You could do:
   pd 'text   0 -20x test'
   pd 'text  80 -20x 1'
   pd 'text 160 -20x 2'
   pd 'text 240 -20x 3'
   pd 'show'

For I table using non-monospace fonts, I imagine that you might need to use a method like this to get the columns to line up anyway?

Thanks Ric;

That should do the trick

It just appeared strange that pd lost all of the spaces in its output.

Stripping white space is a common practice,
such HTML normalization. Instead nbsp is used.
For a table, monospace font is needed.

nbsp_z_=: 1 :'(2*m)$194 160{a.'

pd 'text 0  -20x test',6 nbsp,'1',6 nbsp,'2',6 nbsp,'3'


Here's a helper table builder verb
that will take initial position, list of column widths,
line height and a table of values. The result will be
a series of 'text ...' with corresponding positions.

NB.*pdtable v plot text from table
NB.   (XY;colwidths;lineheight) pdtable table
NB.   eg:  pd (10 _60;0 40 80;_18) pdtable i.2 3
pdtable=: 4 : 0
  'pos cw lh'=. x
  r=. ''
  for_Y. ({:pos)+lh*i.{.$y do.
    for_X. ({.pos)+cw do.
      v=. ":(Y_index,X_index) {:: y
      r=. r,'text ',(":X),'x ',(":Y),'x ',v,LF
   end. end.
   r
)

   (10 _60;0 40 80;_18) pdtable i.2 3
text 10x _60x 0
text 50x _60x 1
text 90x _60x 2
text 10x _78x 3
text 50x _78x 4
text 90x _78x 5
