I guess something along these lines should do the trick (not tested)<br>

//create map etc..<br>

var vectorLayer = new OpenLayers.Layer.Vector("vectors");<br>
map.addLayer(vectorLayer);<br>

track of the min/max x and y, then use those values to set
the extent (the boundaries).

<div>While you can do this in Javascript, we ended up doing
that calculation in the server-side call that got the
points, and sending it over with the json that used to
populate the array of points.</div>

Hi,<br>
I want to draw the line (route using x,y
coordinate points) over the map as vector layer. After
route drawn on map, i want to adjust the zoom level to
show the complete route. How can i do this? Is there
any direct way to do this? If not how to do using math
calculations?<br>
<br>
Regards,<br>
Bala<br>
