I am using a Plotly graph and can give this a title in JavaScript. It will be empty until the user fills in some number fields.

So currently I have the title as:

var layout = {
  title: 'Please enter data to see it graphed',
  font: {size: 12}

and I would like to change this into:

var layout = {
  title: 'Income Chart',
  font: {size: 18}

when a function is called. This function is listening to events on the input field.

I know how to use javascript to change HTML, but would essentially like to use JavaScript to change JavaScript. Is this possible?
