Description of problem:

When checking the log volume in "Observe > Logs" provisioned using Logging UIPlugin, and selecting Explain Log Volume option for time duration more than 1 day, then the date is not available on x-axis because of which it is hard to identify, to which instant the metric is pointing the value to.

Version-Release number of selected component (if applicable):

Cluster Observability Operator 1.0.0/1.1.0/1.2.0

How reproducible:

100%

Steps to Reproduce:

1. Install and configure Red Hat OpenShift Logging 6.2/6.3 with LokiStack.
2. Enable Logging UIPlugin
3. Navigate to "Observe > Logs" menu in webconsole.
4. Select time range greater than 1 day (say Last 1 week)
5. Click on Explain Log Volume option and observe values on x-axis. 

Actual results:

When selecting range for more than 1 day, only time is mentioned on the x-axis but not the associated date.

Expected results:

Date should be visible on x-axis along with time to identify the correct date of the metric.
