I am trying to create something that uses Google charts found here (https://www.w3schools.com/howto/howto_google_charts.asp). However I am wanting to get input using some sort of HTML form element and change the pie chart based on the input.
For example, the w3schools example has the chart initially look like,
var data = google.visualization.arrayToDataTable([
['Task', 'Hours per Day'],
Use AngularJs. Bind the values which you want to make parametric to Angular variables. Also Bind these variables to input fields. So changing these inputs is expected to change pie chart.
