    <p>I am having some trouble with the <a href="http://code.google.com/apis/maps/documentation/reference.html" rel="nofollow noreferrer">Google Maps API</a>. I have an array which holds a ojbect I created to store points.</p> <p>My array and class:</p> <pre><code>var tPoints = []; function tPoint(name) { var id = name; var points = []; var pointsCount = 0; ... this.getHeadPoint = function() { return points[pointsCount-1]; } } </code></pre> <p>tPoint holds an array of <a href="http://code.google.com/apis/maps/documentation/reference.html#GLatLng" rel="nofollow noreferrer">GLatLng</a> points. I want to write a function to return a <a href="http://code.google.com/apis/maps/documentation/reference.html#GLatLngBounds" rel="nofollow noreferrer">GLatLngBounds</a> object which is extended from the current map bounds to show all the HeadPoints.</p> <p>Heres what I have so far..</p> <pre><code>function getBounds() { var mBound = map.getBounds(); for (var i = 0; i &lt; tPoints.length; i++) { alert(mBound.getSouthWest().lat() + "," + mBound.getSouthWest().lng()); alert(mBound.getNorthEast().lat() + "," + mBound.getNorthEast().lng()); currPoint = trackMarkers[i].getHeadPoint(); if (!mBound.containsLatLng(currPoint)) { mBound.extend(currPoint); } } return mBound; } </code></pre> <p>Which returns these values for the alert. (Generally over the US)<br /></p> <blockquote> <p>"19.64258,NaN"<br /> "52.69636,NaN"<br /> "i=0"<br /> "19.64258,NaN"<br /> "52.69636,-117.20701"<br /> "i=1"<br /></p> </blockquote> <p>I don't know why I am getting NaN back. When I use the bounds to get a zoom level I think the NaN value is causing the map.getBoundsZoomLevel(bounds) to return 0 which is incorrect. Am I using <a href="http://code.google.com/apis/maps/documentation/reference.html#GLatLngBounds" rel="nofollow noreferrer">GLatLngBounds</a> incorrectly?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
