Plot is a great package. And it solves 90% of needes
out of the box. Though I have tired a seemingly trivial
specific real-world example and it isn't easy to see
how to do it right.
I need a density plot with custom axis labels
and ability to mark certain cells with short text.
* When I make a density plot with small number of cells
it shows that the X axis marks are off: they mark the
boundaries, whereas I need to mark the cells:
'density' plot +/~i.5
whereas I need like this:
'bar,density' plot +/~i.5 NB. looks like a hack
Is it the official way to get the axis labels against cells?
* Also while it shows the X axis correctly, the problem is
with the Y axis, it remains off by one cell.
* Next, I need custom labels, like xlabel, but to be able to
spread automatically, like continuous labels do: 0 .. 5 .. 10,
not 1 2 3 4 5 6 7 8 9 10. The solution is calculate the spread
with the same 'bar,density' pair:
'bar,density;xlabel 3 8 13 18 23 28' plot +/~i.30
Is there a better way?
* I need to place some kind of marker, like number of short text,
or symbol inside some selective cells, which I can do manually
for specific plot. 'text' could be used, but how to make sure
that it always lands on the correct cell in the data space.
'bar,density;text 130 200 A' plot (10+0.2*i.5);+/~i.5
How to make sure that the text stays in the cell and not
move around with resizing.
I guess it would involve a function that takes data space
coords, like (0,0) for bottom left cell and string 'A' and
will calculate the plot coordinates dynamically.
Or maybe I could superimpose a marker XY-plot on top of
the density plot?
