The expression return $this->options returns the type CMEN\GoogleChartsBundle\GoogleCharts\Options\ChartOptionsInterface which includes types incompatible with the type-hinted return CMEN\GoogleChartsBundle\GoogleCharts\Options\AreaChart\AreaChartOptions.

    public function setOptions(ChartOptionsInterface $options): AreaChart

$options is of type CMEN\GoogleChartsBundle\GoogleCharts\Options\ChartOptionsInterface, but the property $options was declared to be of type CMEN\GoogleChartsBundle\GoogleCharts\Options\AreaChart\AreaChartOptions. Are you sure that you always receive this specific sub-class here, or does it make sense to add an instanceof check?

        return $this;
