I am using the following Highcharts to extract data from a datatable. Highcharts functions okay, but there is a case where I don't want to show the last row from the table because it is the "Total" . Is there a way I can not display last row? This is the code.

$(document).ready(function() {
var allSeriesData = [];
var categories = [];
var table = $("#example1").DataTable({
initComplete: function(settings, json) {
let api = new $.fn.dataTable.Api(settings);
// get the x-axis caregories from the table headings:
var headers = api.columns().header().toArray();
headers.forEach(function(heading, index) {
if (index > 0 && index < headers.length ) {
categories.push($(heading).html());
}
});
// get the seris data as an array of numbers from the table row data:
let rows = api.rows().data().toArray();
rows.forEach(function(row) {
group = {
name: '',
data: []
};
row.forEach(function(cell, idx) {
if (idx == 0) {
group.name = cell;
} else if (idx < row.length ) {
group.data.push(parseFloat(cell.replace(/,/g, '')));
}
});
allSeriesData.push(group);
});
}
});
var myChart = Highcharts.chart("container", {
chart: {
type: "column"
},
title: {
text: "Test Data"
},
xAxis: {
categories: categories
},
series: allSeriesData
});

Just add myChart.series[4].remove();. Other options are using endRow or remove it in the complete callback, but you don't seem to be using the data module.
