Here is the call graph for this function:

◆ setLabelRadius()

ilChartDataPie::setLabelRadius ( $a_value )

Sets the radius at which to place the labels.

If value is between 0 and 1 (inclusive) then it will use that as a percentage of the available space (size of the container), otherwise it will use the value as a direct pixel length.

Parameters

mixed $a_value

Definition at line 51 of file class.ilChartDataPie.php.

    {
        $this->label_radius = $a_value;
    }

◆ setLineWidth()

ilChartDataPie::setLineWidth ( $a_value )

Set line width.

Parameters

int $a_value

Definition at line 28 of file class.ilChartDataPie.php.

        {
                $this->line_width = (int)$a_value;
        }
