[Solved]-Highcharts / jQuery - destroy and rebuild chart with original options-Highcharts

1) is this the right way to destroy and rebuild the chart, or is there a better method?

That's the only way and Highcharts is smart enough so that you don't have to worry about any memory leaks.

2) if this is the way to do it, then how do I get my show/hide/check/uncheck functions to continue to work afterward?

You are recreating the chart but not assigning it to the variable chart again.

$('#resetChart').click(function(){
    chart1.destroy();
    chart1 = new Highcharts.Chart(optionsChart1,highlightSer);
    chart = chart1; // <-------- Add this line here.
});
