What indices have you created? If you haven't created any of your own indices, you may need to click the "Include system indices" at the top right.
By default, Kibana will not show a lot of the indices that other Elastic tools create, since those indices are mostly meant for internal use. It knows they are "internal" because they are named with a leading dot (.). So if you are creating indices with a leading dot, they won't show up there.
If that's not the case, it would still be helpful to know what names you are using.
