after testing several times, this seems to fix the issue:
document.getelementbyid("btn1").addeventlistener("click",function(){
mypiechart.data.datasets[0].data = data1arr;
mypiechart.update();
});
document.getelementbyid("btn2").addeventlistener("click",function(){
mypiechart.data.datasets[0].data = data2arr;
mypiechart.update();
});
