This is a very common issue when it comes to updating charts. Please add the following code at the start of your updateCharts(buttonClick: string) method. 

Chart.helpers.each(Chart.instances, function (instance) {
        instance.destroy();
      });

It will destroy all the previous chart instances before updating. I hope this is what you’re expecting.
