I wanted to get percentage of each slice of pie . I am using chart.js for visualizing feedback results. Below is the code i am using

<script>
        var xValues = ["very satisfied", "satisfied", "neutral", "dissatisifed", "very dissatified"];
        var yValues = {{ faculty_feedback_data }};
        var barColors = [
            "#b91d47",
            "#00aba9",
            "#2b5797",
            "#e8c3b9",
            "#1e7145"
        ];
        faculty_questionnaire = [questions are inserted here ]
        faculty_chart_ids = ["faculty-chart1", "faculty-chart2", "faculty-chart3", "faculty-chart4", "faculty-chart5", "faculty-chart6", "faculty-chart7", "faculty-chart8", "faculty-chart9", "faculty-chart10", "faculty-chart11", "faculty-chart12", "faculty-chart13"]
        for (let i = 0; i < faculty_chart_ids.length; i++) {
            new Chart(faculty_chart_ids[i], {
                type: "pie",
                data: {
                    labels: xValues,
                    datasets: [{
                        backgroundColor: barColors,
                        data: yValues[i]
                    }]
                },
                options: {
                    title: {
                        display: true,
                        text: faculty_questionnaire[i]
                    },
                },    
            });
        }
</script>
