=head1 NAME
Chart::Clicker::Context - A rendering context: Axes, Markers and a Renderer
=head1 VERSION
version 2.90
=head1 SYNOPSIS
  my $clicker = Chart::Clicker->new;
  my $context = Chart::Clicker::Context->new(
    name => 'Foo'
  );
  $clicker->add_to_contexts('foo', $context);
=head1 DESCRIPTION
Contexts represent the way a dataset should be charted.  Multiple contexts
allow a chart with multiple renderers and axes.  See the CONTEXTS section
in L<Chart::Clicker>.
=head2 renderer
Set/get this context's renderer
=head1 ATTRIBUTES
=head2 domain_axis
Set/get this context's domain L<Axis|Chart::Clicker::Axis>.
=head2 markers
An arrayref of L<Chart::Clicker::Data::Marker>s for this context.
=head2 name
Set/get this context's name
=head2 range_axis
Set/get this context's range L<Axis|Chart::Clicker::Axis>.
=head1 METHODS
=head2 add_marker
Add a marker to this context.
=head2 marker_count
Get a count of markers in this context.
=head2 share_axes_with ($other_context)
Sets this context's axes to those of the supplied context.  This is a
convenience method for quickly sharing axes.  It's simple doing:
  $self->range_axis($other_context->range_axis);
  $self->domain_axis($other_context->domain_axis);
