  I want a stacked bar chart that shows preset values that the user can update.

  I have it set up where the first data value updates, but I can’t get the other two and the total to update.

  //get input values
  function graphMe(){
  var static = document.getElementById("inputa").value;
  myChart.data.datasets[0].data[0] = static;
    
    document.getElementById("inputb").value;
  myChart.data.datasets[0].data[1] = static;
    
    document.getElementById("inputc").value;
  myChart.data.datasets[0].data[2] = static;
    
    
  myChart.update();
    }
