carto to use labels in CartoDB maps

labels.cartodb

Just a quick sketch to explain how to use labels in CartoDB:

Something like this should work while we sort out exactly how to release this:

#populated_places_points_2{
  marker-fill:#0099FF;
  marker-line-color:white;
  marker-line-width:1;
  marker-opacity:0.68;
  marker-line-opacity:0.68;
  marker-width:20px;
  marker-placement:point;
  marker-type:ellipse;
  marker-allow-overlap:true;
  text-face-name: "DejaVu Sans Book";
  text-fill:#000;
  text-size:9;
  text-transform:uppercase;
  text-halo-fill:rgba(255,255,255,1);
  text-halo-radius:1;
  text-line-spacing:1;
  text-wrap-width:20;
  text-allow-overlap:true;
  text-name:"[name]";
}

(secret is   text-allow-overlap:true;)

This works for our polygon data, thanks!

For text-name:"[name]"; can I insert a constant? I've tried some different approaches but they don't seem to work, such as:
text-name:"SD + [name]";
text-name:"SD" + "[name]";
text-name:"SD" & "[name]";

Or would I just make a new field and populate that with the constant plus variable data?

Cool! We had this today and while you should be able to, it looks like its broken in the current build. Im afraid you'll have to concatenate for now Simon

Now it's time to play!

Is there a CSS property to force polygon labels to stay inside the polygon? You can see from this (crudely annotated) screenshot that Assembly District 85 partially surrounds AD 84, but the label for 85 is placed within AD 84 (likely because of the polygon's centroid location). http://dl.dropbox.com/u/20314275/cartoDBlabels_outsidedistrict.PNG

I guess I could create a new centroid layer and ensure that each location is within it's parent polygon. But can I do it on the fly with CSS?
