You can also use a number between 0 and a maximum number (such as 100) to represent the exact progress completion status (such as progress percentage). There are two attribute values: value: the amount of work that has been completed. max: How much work is there in total. Note that the value of the value and max attributes must be greater than 0, and the value of value must be less than or equal to the value of the max attribute.
#meter: Tag defines a scalar measurement within a known range or fractional value. Also known as gauge.
