Hey @kp2061 this problem might be happening due to following reason check each one to make it work.

  1. Ensure that you have included the Google Charts library in your HTML file and that you are using the correct version.
  2. Double check your data format and make sure it is in the expected structure.
  3. Ensure that you are using the ‘setCrosshair()’ function correctly.
    var options = {
    crosshair: {
    color: ‘red’,
    orientation: ‘both’,
    selected: {
    color: ‘blue’
