You don't need a new feature to do this. Try using [**Template String**](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals) which allows you to use `${expression}` in string. You can refer to the demo below and try altering the value of `num`: <details> <summary>Code Sample</summary> ``` const num = -5; option = { xAxis: { type: 'category', data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'] }, yAxis: { type: 'value' }, series: [ { data: [120, 200, 150, 80, 70, 110, 130], type: 'bar', showBackground: true, backgroundStyle: { color: 'rgba(180, 180, 180, 0.2)' }, label:{ show: true, color:`${num > 0 ? 'red' : 'blue'}` } } ] }; ``` </details> -- This is an automated message from the Apache Git Service.
