Hello team, i would like to format the tooltip displayed value in columnChart (google). For exemple i'd like to do : 2580000000 / 1000 and return 2580000K in the tootltip. Do you have an option for this ? Thanks by advance

I solved my problem using the tooltip feature. But you should add this option in the documentation

'tooltip' => function ($row) use($columnName, $dividerSign, $params, $format){
                    //Applique un divider si il est définie
                    $dividerRatio  = isset($params['dividerRatio']) && $params['dividerRatio'] != "" &&  $params['dividerRatio'] != 0 ? $params['dividerRatio'] : 1;
                    //Récupère le signe de division
                    $divider = isset($dividerSign[$dividerRatio]) ? $dividerSign[$dividerRatio] : "";
                    
                    return $params['columns'][$columnName]['label'].' : '.number_format($row[$columnName] / $dividerRatio, 0, $format['decimalPoint'], $format['thousandSeparator']).' '.$divider;
                };

but this solution change the style of the tooltip (bold text and background style) and the isHTML option doesn't work. Do you know why ?

'options'=>['tooltip' => ['isHtml' => true]];
