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.
You can find this setting into below xml files in Xconnect site-
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.
