-- Deal with antialiasing for GD 2 and up

--Interesting Idea!

I'd like to change "x" axis label color depending on current label value.
If label starts with "SOMETHING" I'd like to have label in red
otherwise in black color.
I wrote a function as follows:

sub xLabelColor
{
        my $value = shift;
        my $ret;
        if ($value =~ /^SOMETHING/i){
                $ret = [qw(red)];
        }
        else
        {
                $ret = [qw(black)];
        }
        return $ret;
}

and then set as a grapgh attribute:

$my_graph->set( 'axislabelclr' => \&xLabelColor );

--Flexible colours. Allow #ffeedd notation, on the fly. Allow
conversions. Allow addition of single colours, by name.

---	Make it possible to create image maps with this
	This may create the necessity for some sort of dry-run mode, and
	creation of the gd object on demand, instead of directly.

I'm using your clever little graph system and wonder if it can support
nested data sets. I want to show two data sets side by side, but each
data set itself consists of a set of data which I want to show piled one
on top of the other.

I tried the following data set, with two_axes set to 1 and overwrite set
to 2. I didn't like it. Any ideas.

@data = (
    ["1st","2nd","3rd","4th","5th","6th","7th", "8th", "9th"],
	    [    [5,5,5],   [5,5,5],   [5,5,5],   [5,5,5],   [5,5,5],
		[5,5,5],
		+[5,5,5],    [5,5,5],    [5,5,5]],
		    [    [5,5,5],   [5,5,5],   [5,5,5],   [5,5,5],   [5,5,5],
			[5,5,5],
			+[5,5,5],    [5,5,5],    [5,5,5]],
			);

  1) Is there any way to make the y-axis count upwards negative instead
  of upwards positive?

  Answer: negate all the value,s and use y_number_format with a sub
  reference. (Make this into an example!)

  2) Is there a way to set a minimum step value for axis ticks?  All of
  my data are integers.  When I make a line graph, and the max is 2 and
  the min is -1, the ticks are divided into 0.5 ticks.  No matter how
  small the range in data, I'd like the minimum difference in ticks to
  always not be less than 1.

  Check whether this is doable

	1 - $g->('x_number_format' => \&x_format) only works for numerical 
	x axes. Can this be expanded?

	No matter what I do, I can't get the first point to appear at
	where the X and Y axes meet; instead, it appears one tick mark to
	the right of zero on the X axis.

	1. Is it possible to do away with the blank space between the
	y-axis and the graph output and the trailing space (area, lines,
	linespoints)?

	2.  Is it possible to create the output without either or both axes?

From: "Thierry Botten" <Botten.Thierry@talkline.de>

	My suggestions :
	1) Display the data used for each chart inside the chart (does
	this work?)
	2) Display the date (and hour?) the graph was created?
	3) Maybe define your own delimiter character (e.g i like '|' and
	others use '~', etc...)

	- I wanted to have different line widths for the different lines
	  on one graph: I changed lines.pm. The parameter line_width is
	  now an array and works in the  same way as line_type. You will
	  find in attached my new lines.pm and a diff of the original and
	  this file.

Mixed Graphs, all graphs,

	Allow setting of individual options per data set:

	It will not be trivial at all to implement this, but it will require a
	lot of tweaking of the code. I will have a look at it, and try to
	estimate the amount of effort needed. Most likely it means that each
	option needs to be able to take either a single value, or a array ref.
	If it's an array ref, then it needs to take the appropriate setting
	out of the array, or the last one. Something like that. It would
	require writing a wrapper function that does that, and making sure
	that wrapper gets called for all settings that would apply to
	individual data sets.

	mgjv - Should be using label formatting routine. Need to test?

	1.
	Is there any reason why pie charts can't have legends? If there is
	a really thin slice a legend is a good way to get the information
	across without polluting the graph with a long data title, (and
	keep it readable).

	2.
	Still on pie charts it would also be nice to be able to get the
	data percentages and the totals in the pie.

	For example one of my pies is a breakdown of the Operating System
	of different machines around the office.

	If the data breaks down

	Linux - 45%
	Solaris - 30%
	Windows NT -25%

	Total system = 100

	It would be nice to have legends with the OS Names, and have
	offset lines from the pie which show the percentages.

	3.
	Bar charts lend themselves to presenting the data that make up the
	datapoint above the bar, whether this is an absolute number, or a
	percentage.
