Netbeans autoformat failed to format the following code :
-----------------------------------
<script type="text/javascript">
    $(document).ready(function () {
        $('#graphiqueHistoriqueEQS').highcharts({
        chart: {
        type: 'column',
        },
                title: {
                text: 'mon Titre',
                },
                xAxis: {
<?= metaObject::getCategories() ?>
                },
<?= metaObject::getSeries(metaObject::getHistorique($secteur, $annee - 1), metaObject::getHistorique($secteur, $annee - 2)); ?>
        });
    });
</script>
-----------------------------------
If I add "keyword:" before my first <?= ... ?> the auto-format work nice.

Note : the auto-format work correctly for the same code, with just a php value eg :
-----------------------------------
<script type="text/javascript">
    $(document).ready(function () {
        $('#graphiqueHistoriqueEQS').highcharts({
            chart: {
                type: 'column',
            },
            title: {
                text: 'Historique EQS',
            },
<?= highchartsMetaObject::getSeries(directionMetaObject::getHistoriqueEQS($secteur, $annee - 1), directionMetaObject::getHistoriqueEQS($secteur, $annee - 2)); ?>
        });
    });
</script>
