SPA app - reusing chart or not - or best approach

[OpreaFlorin]

Hi. I have a SPA application. In one section I have a chart. This chart is initialized only if the user reaches that section. Also, when the user visits that section again, the chart should be reused.
At this moment I have a variable that remembers if that chart has already been created (to update it) or if it is already created and it is only necessary to update it.

var flag_chart_need_initialization = true;
var my_chart;

function display_chart() {
    var my_chart_options = {
        ...
    }; // chart data
    if (flag_chart_need_initialization) {
        flag_chart_need_initialization = false;
        my_chart = new ApexCharts(document.querySelector("#chart-users"), my_chart_options);
        my_chart.render();
    } else {
        my_chart.updateOptions(my_chart_options, false, true, false);
    }
}

How do you proceed and what is the best approach?
Is it a good idea to update it or should I delete the old one and create a new chart always?
How do you proceed?
Thank you
