Using an attribute value in a TemporalRenderer::observationRenderer

[PremRadhakrishnan]

What I would like to do is use an attribute of the feature being rendered in the Symbol for the observationRenderer. Basically I would like the symbol to have a angle of a SimpleMarker symbol be defined using an attribute of the feature being rendered. Lets say the attribute is called "heading" , I want the angle of the SimpleMarker symbol used to render the feature to be equal to the "heading" attribute.

Thanks in advance

You'll need to create a custom renderer for this by extending Renderer:
