Histogram, log line not working as expected in latest version of grafana & loki

Hi I am using latest version of grafana and configured loki inside it. But on the explore page of loki few features are not working as expected. Not sure if I am missing something on these points.

Following are the points

  1. Histogram not showing selected Date & time ( timeline )

    Q. How should I enable that configuration where in i would see same histogram as of the filter which I have selected.

  2. Range showing only 1 min log
    Here I want to see the full range which I have selected as a filter. But grafana only showing 1 min range. If I want to see more logs then I have to click on “Older Logs” button. Is it possible to see full range instead of 1 min range?
