you will need to adjust the data accordingly

based on the Series definition...

Series: [
  "Event",
  "Registered",
  {"role":"annotation"},
  "Participated",
  {"role":"annotation"},
  "Offered",
  {"role":"annotation"}
]

a typical row may look like this...

Row: [
  "Test",  // Event
  40,      // Registered
  "40",    // Registered annotation
  30,      // Participated
  "30",    // Participated annotation
  0,       // Offered
  null     // Offered annotation
]

use null for the annotation when the column value is zero
