I have been trying to embed a viz into my wordpress website. I followed the suggestions in this discussion (Embed Code for Wordpress.com does not work) and installed the plug so finally able to embed. But unfortunately I can't seem to get rid of the Tableau public website header and footer. I cam across this tableau post (How to Fix Your iFrame | Tableau Public ) but it appears the plugin code has been updated for this aspect and still doesn't work for me.
This is the code inserted into wordpress using the plugin:
[tableau server="public.tableausoftware.com" workbook="Test_1371" view="Lifeisfinite_dashboard" tabs="no" embed="yes" toolbar="no" revert="" refresh="yes" linktarget="" width="800px" height="600px"][/tableau]
Have you tried adding showvizhome="no" to your embed code?
