=head1 DESCRIPTION
Tk::ForDummies::Graph::Mixed is an extension of the Canvas widget. It is an easy way to build an
interactive graph into your Perl Tk widget. The module is written entirely in Perl/Tk.
In the same graph, you can create lines, bars, areas, line points, points.
You can change the color, font of title, labels (x and y) of the graph.
You can set an interactive legend.
The axes can be automatically scaled or set by the code.
You can use 3 methods to zoom (vertically, horizontally or both).

=item Name: B<Typemixed>
=item Class: B<TypeMixed>
=item Switch: B<-typemixed>
This controls the graph types to display in the same order as data set. This should be a reference to an array of graph types.
The different types are : B<areas>, B<bars>, B<lines>, B<dashlines> and B<points>
-typemixed => [ 'areas', 'bars', 'lines' ]
-typemixed => [ 'lines', undef, 'areas' ]
values that are undefined will be set to -defaulttype option.
Default : B<undef>
=item Name: B<Defaulttype>
=item Class: B<DefaultType>
=item Switch: B<-defaulttype>
The type of graph to draw for data sets that either have no type set, or that have undef type set.
The different types are : B<areas>, B<bars>, B<lines>, B<dashlines> or B<points>
-defaulttype => 'bars',
Default : B<'lines'>

=head1 WIDGET METHODS
The Canvas method creates a widget object. This object supports the
configure and cget methods described in Tk::options which can be used
to enquire and modify the options described above.
=head2 add_data
=over 4
=item I<$GraphDummies>->B<add_data>(I<\@NewData, ?$legend>)
This method allows you to add data in your graph. If you have already plot data using plot method and
if you want to add new data, you can use this method.
Your graph will be updade.
=back
=over 8
=item *
I<Data array reference>
Fill an array of arrays with the values of the datasets (I<\@data>).
Make sure that every array has the same size, otherwise Tk::ForDummies::Graph::Lines
will complain and refuse to compile the graph.
my @NewData = (1,10,12,5,4);
$GraphDummies->add_data(\@NewData);
If your last graph has a legend, you have to add a legend entry for the new dataset. Otherwise,
the legend graph will not be display (see below).
=item *
I<$legend>
my @NewData = (1,10,12,5,4);
my $legend = 'New data set';
$GraphDummies->add_data(\@NewData, $legend);
=back
=head2 clearchart
=over 4
=item I<$GraphDummies>->B<clearchart>
This method allows you to clear the graph. The canvas
will not be destroy. It's possible to I<redraw> your
last graph using the I<redraw method>.
=back
=head2 delete_balloon
=over 4
=item I<$GraphDummies>->B<delete_balloon>
If you call this method, you disable help identification which has been enabled with set_balloon method.
=back
=head2 disabled_automatic_redraw
=over 4
=item I<$GraphDummies>->B<disabled_automatic_redraw>
When the graph is created and the widget size changes, the graph is automatically re-created. Call this method to avoid resizing.

=back
=head2 display_order
=over 4
=item I<$GraphDummies>->B<display_order>(I<\@types>)
Manage the display order of the various graphs.
$GraphDummies->display_order( [qw/ areas bars lines dashlines points /] );
In this example, the area will be in the background, followed by bars, lines, dashlines and points.
=back
=head2 display_values
=over 4
=item I<$GraphDummies>->B<display_values>(I<\@data_point_value>)
To plot the value of data near the point (Line, Spline, Point, Area graph), call this method to control in a generic manner.
my @data_point_value = (
[ 9, 2, 5, 6, 3, 1, 1, 3, 4 ], # The first line data
undef, # The second line data
[ 'A', 'B', undef, 'D', 'E', 'F', 'G', 'H', undef ], # The third line data
);
$GraphDummies->display_values( \@data_point_value );
In this example, values are added above each point of the first and third graph.
The second line is undef, no values are printed in the graph.
B value is printed above the second point of the third line data.
=back
=head2 enabled_automatic_redraw
=over 4
=item I<$GraphDummies>->B<enabled_automatic_redraw>
Use this method to allow your graph to be recreated automatically when the widget size change. When the graph
is created for the first time, this method is called.
$GraphDummies->enabled_automatic_redraw;
=back
=head2 plot
=over 4
=item I<$GraphDummies>->B<plot>(I<\@data, ?arg>)
To display your graph the first time, plot the graph by using this method.
=back
=over 8
=item *
I<\@data>
Fill an array of arrays with the x values and the values of the datasets (I<\@data>).
Make sure that every array have the same size, otherwise Tk::ForDummies::Graph::Mixed
will complain and refuse to compile the graph.
my @data = (
[ '1st', '2nd', '3rd', '4th', '5th', '6th', '7th', '8th', '9th' ],
[ 1, 2, 5, 6, 3, 1.5, 1, 3, 4 ],

[ 1, 2, 52, 6, 3, 17.5, 1, 43, 10 ]
);
@data have to contain a least two arrays, the x values and the values of the datasets.
If you don't have a value for a point in a dataset, you can use undef,
and the point will be skipped.
[ 1, undef, 5, 6, 3, 1.5, undef, 3, 4 ]
=item *
-substitutionvalue => I<real number>,
If you have a no real number value in a dataset, it will be replaced by a constant value.
Default : B<0>
my @data = (
[ '1st', '2nd', '3rd', '4th', '5th', '6th', '7th', '8th', '9th' ],

);
$GraphDummies->plot( \@data,
-substitutionvalue => '12',

# mistake, -- and NA will be replace by 12
-substitutionvalue have to be a real number (Eg : 12, .25, 02.25, 5.2e+11, ...)
=back
=head2 redraw
Redraw the graph.
If you have used clearchart for any reason, it is possible to redraw the graph.
Tk::ForDummies::Graph::Mixed supports the configure and cget methods described in the L<Tk::options> manpage.
If you use configure method to change a widget specific option, the modification will not be display.
If the graph was already displayed and if you not resize the widget, call B<redraw> method to
resolv the bug.
...
$fenetre->Button(-text => 'Change xlabel', -command => sub {
$GraphDummies->configure(-xlabel => 'red');
}
)->pack;
...
# xlabel will be changed but not displayed if you not resize the widget.
...
$fenetre->Button(-text => 'Change xlabel', -command => sub {

$GraphDummies->redraw;
}
