Hi! I am using chartJs radar for PDF view with export, of the five points of the radar, only the data of two points is shown correctly. I think the problem could be solved if the middle point of the radar takes the value 0. The scale is from 0 to 1. But I can't establish that configuration.

$average_app_margin = $this->dataStore('average_margin_application')->toArray();

                if (!count($average_app_margin)) {
                    echo '<div class="d-flex justify-content-center">
                                <span class="text-info text-sm-center">No data available</span>
                            </div>';
                } else {
                    foreach ($average_app_margin as &$row) {
                        $margin = floatval($row['total_margin'] ?? 0);
                        $row['total_margin'] = number_format($margin, 2, '.', '');
                    }
                  }            

                RadarChart::create(array(
                    //"title" => "Margin per Application",
                    "dataSource" => $average_app_margin,
                        "columns" => array(
                            "job_application" => [
                                "label" => "Application"
                            ],
                            "total_margin" => [
                                "label" => "Total Margin",
                                "type" => 'number',
                                "suffix" => "%",
                            ],
                        ),
                        "showLegend" => false,
                        "widthHeightAutoRatio" => 1.3,
                        "options" => [
                            "scales" => [
                                "r" => [
                                    "suggestedMin" => 0,  
                                    "suggestedMax" => 100, 
                                    "ticks" => [
                                        "beginAtZero" => true,  
                                    ],
                                ],
                            ],
                        ],
                        
                    ));

Hi, You do this :

"options" => [
    "scales" => [
        "ticks" => [
            "beginAtZero" => true,
             "suggestedMin" => 0,
            "suggestedMax" => 100
        ]
    ]
]

H! It hasn't worked for me

Can you be more specific? It would be better if there were illustrations.

I continued researching and testing and I managed to solve it like this. Thank you very much for your help!

"options" => [
                                "scale" => [ 
                                "ticks" => [ 
                                    "beginAtZero" => true, 
                                    "suggestedMin" => 0, 
                                    "suggestedMax" => 100, 
                                ], 
                                "pointLabels" => [ 
                                    "fontSize" => 12,   
                                ], 
                             ]
                       ]      

Glad I was able to help you out a little. Helping you also helped me learn a few things, like how to easily fix similar errors in the future.
