rpress_pie_graph_output

Filters the HTML and script output of a pie graph.

Runs when RPRESS_Pie_Graph builds its markup, after the chart script and containers are rendered into a buffer. The output is only built when the graph has data. The result is later passed through wp_kses by display(), which allows only script and div tags with limited attributes.

Parameters#

Parameter	Type	Description
$output	string	The rendered script and container markup.
$graph_id	string	The unique ID generated for this graph.
$data	array	The label => value data being plotted.
$options	array	The pie graph options after defaults are applied.

Return value#

string. The markup to print.

Example#

function my_pie_graph_output( $output, $graph_id, $data, $options ) {
	return $output . '<div id="my-pie-note-' . esc_attr( $graph_id ) . '" class="my-pie-note"></div>';
}
add_filter( 'rpress_pie_graph_output', 'my_pie_graph_output', 10, 4 );
