NAME

Google::Chart::Data - Draw a chart with Google Chart

SYNOPSIS

Google::Chart::Data->new;

WARNING

This is a very early alpha release. It is more a proof of concept, but for very simple cases it already works. Documentation and more complete support of the Google Chart API will follow shortly. For now, the code more or less is the documentation. Patches welcome.

DESCRIPTION

This set of classes uses the Google Chart API - see http://code.google.com/apis/chart/ - to draw charts.

METHODS

clear_max_value
$obj->clear_max_value;

Clears the value.

clear_value_sets
$obj->clear_value_sets;

Deletes all elements from the array.

count_value_sets
my $count = $obj->count_value_sets;

Returns the number of elements in the array.

index_value_sets
my $element   = $obj->index_value_sets(3);
my @elements  = $obj->index_value_sets(@indices);
my $array_ref = $obj->index_value_sets(@indices);

Takes a list of indices and returns the elements indicated by those indices. If only one index is given, the corresponding array element is returned. If several indices are given, the result is returned as an array in list context or as an array reference in scalar context.

max_value
my $value = $obj->max_value;
$obj->max_value($value);

A basic getter/setter method. If called without an argument, it returns the value. If called with a single argument, it sets the value.

max_value_clear
$obj->max_value_clear;

Clears the value.

pop_value_sets
my $value = $obj->pop_value_sets;

Pops the last element off the array, returning it.

push_value_sets
$obj->push_value_sets(@values);

Pushes elements onto the end of the array.

set_value_sets
$obj->set_value_sets(1 => $x, 5 => $y);

Takes a list of index/value pairs and for each pair it sets the array element at the indicated index to the indicated value. Returns the number of elements that have been set.

shift_value_sets
my $value = $obj->shift_value_sets;

Shifts the first element off the array, returning it.

splice_value_sets
$obj->splice_value_sets(2, 1, $x, $y);
$obj->splice_value_sets(-1);
$obj->splice_value_sets(0, -1);

Takes three arguments: An offset, a length and a list.

Removes the elements designated by the offset and the length from the array, and replaces them with the elements of the list, if any. In list context, returns the elements removed from the array. In scalar context, returns the last element removed, or undef if no elements are removed. The array grows or shrinks as necessary. If the offset is negative then it starts that far from the end of the array. If the length is omitted, removes everything from the offset onward. If the length is negative, removes the elements from the offset onward except for -length elements at the end of the array. If both the offset and the length are omitted, removes everything. If the offset is past the end of the array, it issues a warning, and splices at the end of the array.

unshift_value_sets
$obj->unshift_value_sets(@values);

Unshifts elements onto the beginning of the array.

value_sets
my @values    = $obj->value_sets;
my $array_ref = $obj->value_sets;
$obj->value_sets(@values);
$obj->value_sets($array_ref);

Get or set the array values. If called without an arguments, it returns the array in list context, or a reference to the array in scalar context. If called with arguments, it expands array references found therein and sets the values.

value_sets_clear
$obj->value_sets_clear;

Deletes all elements from the array.

value_sets_count
my $count = $obj->value_sets_count;

Returns the number of elements in the array.

value_sets_index
my $element   = $obj->value_sets_index(3);
my @elements  = $obj->value_sets_index(@indices);
my $array_ref = $obj->value_sets_index(@indices);

Takes a list of indices and returns the elements indicated by those indices. If only one index is given, the corresponding array element is returned. If several indices are given, the result is returned as an array in list context or as an array reference in scalar context.

value_sets_pop
my $value = $obj->value_sets_pop;

Pops the last element off the array, returning it.

value_sets_push
$obj->value_sets_push(@values);

Pushes elements onto the end of the array.

value_sets_set
$obj->value_sets_set(1 => $x, 5 => $y);

Takes a list of index/value pairs and for each pair it sets the array element at the indicated index to the indicated value. Returns the number of elements that have been set.

value_sets_shift
my $value = $obj->value_sets_shift;

Shifts the first element off the array, returning it.

value_sets_splice
$obj->value_sets_splice(2, 1, $x, $y);
$obj->value_sets_splice(-1);
$obj->value_sets_splice(0, -1);

Takes three arguments: An offset, a length and a list.

Removes the elements designated by the offset and the length from the array, and replaces them with the elements of the list, if any. In list context, returns the elements removed from the array. In scalar context, returns the last element removed, or undef if no elements are removed. The array grows or shrinks as necessary. If the offset is negative then it starts that far from the end of the array. If the length is omitted, removes everything from the offset onward. If the length is negative, removes the elements from the offset onward except for -length elements at the end of the array. If both the offset and the length are omitted, removes everything. If the offset is past the end of the array, it issues a warning, and splices at the end of the array.

value_sets_unshift
$obj->value_sets_unshift(@values);

Unshifts elements onto the beginning of the array.
