Cannot set Zoom with single marker present #18

Closed joeytheman closed 13 years ago

joeytheman commented 13 years ago

If a single element is present in @json,the map shows fully-zoomed in, ignoring the zoom option. Works fine with 2 or more elements.

<%= gmaps({
"map_options" => { "type" => "SATELLITE", "center_longitude" => 180, "zoom" => 3, "auto_adjust" => true},
"markers"     => { "data" => @json } } )
%>

Passing auto_zoom => false fixes the issue.

Not sure if that really works. Yes it will override the condition for a single marker, but when there are multiple markers again, you really want the autozoom => true, no? Setting maxZoom and minZoom helps but it limits how far users can zoom. Neither is a perfect solution.
