    <p>I am trying to render directions for 48 waypoints, but google only allows 8 waypoints to be rendered per request. so I do multiple requests (in my case 6). However, the API somehow doed fitBounds() for the last request.</p> <p>How can I show all the 48 waypoints in one map using fitBounds() and/or setZoom()</p> <p>My code is as below: - </p> <pre><code>function DisplayDirection(directionList){ var interval = 8; // upper bound for usage limits in google directions API is 8 var startIndex =0; var maxmimumIndex = directionList.length-1; // Total number of waypoints in this route var partialEndIndex = interval-1; // end waypoint at start var iteration = 0; // loop controler directionsService = new google.maps.DirectionsService(); var resultSet = new Array(); var directionsDisplayList = new Array(); var resultsCached = 0; var bounds = new google.maps.LatLngBounds(); do { //do...while to iterate over multiple requests iteration++; if(iteration&gt;1){ startIndex = startIndex+interval; partialEndIndex = startIndex+interval; } var directionsDisplay = new google.maps.DirectionsRenderer({ markerOptions: { visible:false } }); directionsDisplayList.push( directionsDisplay ); directionsDisplayList[iteration-1].setMap(map); var origin = directionList[startIndex]; var destination = partialEndIndex &lt; maxmimumIndex ? directionList[partialEndIndex]:directionList[maxmimumIndex]; waypoints = new Array(); for(var i=startIndex+1;i&lt;partialEndIndex;i++){ if(i&gt;maxmimumIndex){ break; } waypoints.push( { location:directionList[i], stopover:true } ); latlong = directionList[i].split(","); // lat = latlong[0]; // lng = latlong[1]; // bounds.extend (new google.maps.LatLng(lat,lng)); //extend the bounds } var request = { origin: origin, destination: destination, waypoints : waypoints, provideRouteAlternatives:false, travelMode: google.maps.TravelMode.WALKING, unitSystem: google.maps.UnitSystem.METRIC } directionsService.route(request, function(result, status) { if(status == google.maps.DirectionsStatus.OK) { //Cashe the results to render directions// resultSet.push(result); if(resultSet.length==iteration){ for(var i=0; i&lt;iteration; i++){ directionsDisplayList[i].setDirections(resultSet[i]); } map.fitBounds(bounds); } } }); }while (partialEndIndex &lt;= maxmimumIndex); } </code></pre>

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.
