The Unresolved Tickets metric supports only 50 data points. For example, in any widget where this metric is used, you can only view upto 50 values for this metric over time. Due to this, the values show up as 0 after the limit of 50 data points is exhausted.

If you have a need to view more data points for this metric, you can use the following options:

- Use the Unresolved Tickets metric in another widget to view.
- Change the group by condition to result in a lower number of data points. For example, if you are grouping your data by days, you can consider grouping by weeks and so on.
- Use appropriate filters to restrict the time duration for which you want to view this metric, such that the number of data points is less than 50.
