[Octave-bug-tracker] [bug #52135] bar cannot plot two stacked bars

[Dan Sebald]

Follow-up Comment #15, bug #52135 (project octave):

I agree that there is some question as to what is actually a grouped versus
conventional bar graph in the vector case.

But the patch you created is close.  I think the issue is that you haven't
covered every instance of rows/cols with the new mod.  My previous post had a
"verbatim" issue, so I'm reposting.

The examples work, but it may have broken this case [similar to bar(1:10)]:


octave:4> h = bar ([1 2], [3 4])
error: bar: length of X and Y must be equal
error: called from
    __bar__ at line 123 column 5
    bar at line 118 column 16


Maybe this test:


  ngrp = rows (x);
  if (ngrp != rows (y))
    error ("%s: length of X and Y must be equal", func);
  endif


needs to be on cols(y) rather than rows(y).  Also, there is a rows() here
after swapping x and y that should be double checked (should it be y = x.'?):


    if (isscalar (y) && ! isscalar (x))
      ## "y" is actually "width" argument
      y = x;
      x = [1:rows(y)]';
      idx = 2;
