I noticed recently that my published iframe map adjusts to whatever the zoom and centering is for that map on the cartodb site. So if I'm playing around with the cartodb map on cartodb, say exploring particular regions of the map, this will have a direct impact on what my website users see in the embedded map.
Is there a way to avoid this? I don't see any parameters for setting center or zoom in the iframe code:
<iframe width='100%' height='520' frameborder='0' src='http://sanjuro.cartodb.com/viz/10f021cc-b7a5-11e4-a4dd-0e853d047bba/embed_map' allowfullscreen webkitallowfullscreen mozallowfullscreen oallowfullscreen msallowfullscreen></iframe>
