Which version of Sitecore you are on? If you are working on Sitecore 9.x then I would suggest to follow below steps to show anonymous data to Experience profile.
Update IndexAnonymousContactData setting to true by default this is false in XConnect website.
<IndexAnonymousContactData>true</IndexAnonymousContactData>
You can find this setting into below xml files in Xconnect site-
/App_data/jobs/continuous/IndexWorker/App_data/Config/Sitecore/SearchIndexer/sc.Xdb.Collection.IndexerSettings.xml
and
/App_data/Config/sitecore/SearchIndexer/sc.Xdb.Collection.IndexerSettings.xml
I think just making these changes you would be able to see unknown user data in Experience profile.
And if you are using Sitecore 8.2 then below is the configuration.
<setting name="ContentSearch.Analytics.IndexAnonymousContacts" value="false"/>
I hope this can solve your issue but still if you are not able to see the data let me know.
