IIs it possible to rotate a feature based on a column?

Question

Is it possible to get a feature and rotate the graphic based upon a field of data in that feature?

This was a good tutorial,

Renderer with proportional symbols and rotation | ArcGIS API for JavaScript

And, I was able to see how to rotate and scale simple markers, how would I grab the current graphic for a feature and then rotate it?

Thanks,

Morgan

For FeatureLayer, I think it will be null unless you define it at client side.

You can consider using ArcGISDynamicMapServiceLayer  and it's DynamicLayerInfos which can return the current rendering information.

Is there a way to get my current renderer for my feature layer?

If it always null when i try and get it from the feature layer class.

In that case you can simply apply the render for your layer. It's there in the sample that you are using.

var markerSym = new SimpleMarkerSymbol().setPath("M14.5,29 23.5,0 14.5,9 5.5,0z");
      markerSym.setOutline(new SimpleLineSymbol().setWidth(0.5));
      markerSym.setColor(new Color("red"));
      var renderer = new SimpleRenderer(markerSym);
      renderer.setRotationInfo({
        field:"WIND_DIRECT",
        type:"geographic"
      });
      renderer.setSizeInfo({
        field:"WIND_SPEED",
        minSize:3,
        maxSize:20,
        minDataValue:5,
        maxDataValue:50
      });
      layer.setRenderer(renderer);
