I have a GraphicsLayer where I show some TextSymbol's. They are place in position and show correctly. The problem is that they are geographically close and the different texts for each position show up on the map like a mass of unreadable text until you zoom in and get close to them. So we thought that we may show the layer only after some position of the zoom. I have seen this effect in other layers but don't know how to create it. Any ideas? Thanks!
