<chart-line>.options
requires an Object
, which means optionsData
should be an Object
. You’ve assigned a string
to that property (and a malformed JSON string at that), but you should be assigning the actual JSON object like this:
constructor() {
super();
this.optionsData = {animation: {duration: 0}};
}
or more simply:
constructor() {
super();
this.optionsData = {animation: false};
}
