Hi Kenny,
Would it be sufficient for you to just have a point on the map that gets
styled as a circle with a certain radius? Then it's quite easy: [1].

Hi Guys,
I have been trying for ages and can't seem to get this working,
Does anyone have a simple function for drawing a circle?
I mean I want to pass certain variables via a link and it should simply draw
a circle on the map.
Ie:

Hi Chris,
Having trouble figuring out how to adapt the example from a new vector to
existing layer.

Okay, I got what the numbers are. I'm good to go for now.

Excellent. Thanks for the response. I will play around with this. One
quick question, and this might sound stupid, but in the example:
OpenLayers.Renderer.symbol.lightning = [0,0, 4,2, 6,0, 10,5, 6,3, 4,5, 0,0];
What do the points mean 0,0 and 4,2 and 6,0 etc. What do the numbers

Hi,
You can create your own symbols
http://openlayers.org/dev/examples/graphic-name.html
OpenLayers.Renderer.symbol.lightning = [0,0, 4,2, 6,0, 10,5, 6,3, 4,5, 0,0];
OpenLayers.Renderer.symbol.rectangle = [0,0, 10,0, 10,4, 0,4, 0,0];
Or you use an image as symbol.

To compute the minimum distance to the line, you can use the formula

You can also play with the feature style.
You can make a 'hidden' style that turns the opacity down to 0.
Then your slider could change the render intent on certain features.
It really just depends on if your are trying to hide a bunch at once or a few
at a time.

It only happens if the WFS layer is the first one in the layers stack, so

I have the same setup but when layer is created with visibility: false
no requests are made until visibility is changed.
Are you sure you use the last trunk version. I believe there has been

using trunk I see that a vector layer with a BBOX strategy and a WFS
