I want to change the font size in here
I add this options in my barchart class.
                                    "options"=>[
                                        "plugins"=>[
                                            "legend"=>[
                                                "labels" => [
                                                    "font"=> [
                                                        "size"=>12,
                                                    ]
                                                ],
                                            ],
                                        ],
                                    ],
But it's still not changing. I following the options based on googlechart documentation
