Yes, your edgewise gauges look really good. The only suggestion I have is to allow the developer to choose the width &/or style of the pointer. Sometimes the pointer can get lost in the background so it should stand out. Maybe add a drop shadow to the pointer or a black outline around the pointer? Or a triangular pointer? There was a triangular pointer in one of the samples I uploaded. Apart from that minor improvement, I think you nailed it.
Great minds think alike. ROFLThis is already in the to do list .
