Calling update() on

Answer 1

I tried neaumusic solution, but later found out that the only problem with destroy is the scope.

var chart;

function renderGraph() {
    // Destroy old graph
    if (chart) {
        chart.destroy();
    }

    // Render chart
    chart = new Chart(
        document.getElementById(idChartMainWrapperCanvas),
        chartOptions
    );
}

Moving my chart variable outside the function scope, got it working for me.
