i found the solution and the solution is to set the data inside a dictionary
<script>
SubjectData=[]
{{#each table1}}
{{#each this.Classes}}
SubjectData['subjects_{{../Level}}_{{this.Class}}'] = {{{toJS Subjects}}};
Highcharts.setOptions({ plotOptions: { series: { animation: false } } });
Highcharts.chart('container-chart-{{../Level}}-{{this.Class}}', {
credits: { enabled: false },
chart: { backgroundColor: 'transparent' },
title: { text: '', align: 'right' },
xAxis: { categories: SubjectData['subjects_{{../Level}}_{{this.Class}}'].map(subject => subject.Subject), labels: { overflow: 'justify', style: { fontSize: '10px' }, rotation: -65 }},
yAxis: {title: { text: 'الدرجات' },opposite: true},
tooltip: { valueSuffix: ' million liters' },
plotOptions: { series: { borderRadius: '25%',dataLabels: { enabled: true }}},
series: [
{ type: 'column', name: 'اقل درجة', data: SubjectData['subjects_{{../Level}}_{{this.Class}}'].map(subject => parseInt(subject.MinTotal, 10)) },
{ type: 'column', name: 'المتوسط', data: SubjectData['subjects_{{../Level}}_{{this.Class}}'].map(subject => parseInt(subject.MeanTotal, 10)) },
{ type: 'column', name: 'اعلى درجة', data: SubjectData['subjects_{{../Level}}_{{this.Class}}'].map(subject => parseInt(subject.MaxTotal, 10)) }
]
});
Highcharts.chart('highcharts-chart-{{../Level}}-{{this.Class}}', {
credits: { enabled: false },
chart: { backgroundColor: 'transparent', type: 'column' },
title: { text: '' },
xAxis: { categories: SubjectData['subjects_{{../Level}}_{{this.Class}}'].map(subject => subject.Subject), labels: { style: { fontSize: '10px' }, rotation: -65 } },
yAxis: { allowDecimals: false, min: 0, title: { text: 'عدد الطلاب' }, opposite: true },
tooltip: { format: '<b>{key}</b><br/>{series.name}: {y}<br/>' + 'Total: {point.stackTotal}' },
plotOptions: { column: { stacking: 'normal' } },
series: [
{ name: 'ممتاز', data: SubjectData['subjects_{{../Level}}_{{this.Class}}'].map(subject => subject.Excellent_count), stack: 'order' },
{ name: 'جيد جدا', data: SubjectData['subjects_{{../Level}}_{{this.Class}}'].map(subject => subject.Very_Good_count), stack: 'order' },
{ name: 'جيد', data: SubjectData['subjects_{{../Level}}_{{this.Class}}'].map(subject => subject.Good_count), stack: 'order' },
{ name: 'مقبول', data: SubjectData['subjects_{{../Level}}_{{this.Class}}'].map(subject => subject.Pass_count), stack: 'order' },
{ name: 'ضعيف', data: SubjectData['subjects_{{../Level}}_{{this.Class}}'].map(subject => subject.Weak_count), stack: 'order' }
]
});
{{/each}}
{{/each}}
</script>
