Update chart from user input

[sherrylking]

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();
  }
