how to remove "powered by zingchart" in angularjs piechart

Question

Is there any way to remove "powered by zingchart" text in zingchart piechart ?

I saw some answers in web, that need to add license key.

Do we have any other way, without adding the license key ?

Answer 1

Try this...

div[id$="license"] {
  display: none !important;
}

Tested here

Still, this is a illegal way. Use a valid license key for legal and permanent usage.
