SimpleFillSymbol not showing up

MehulMarolia — Thu, 08 Nov 2012 16:46:22 GMT

Hi,

I am new to ArcGIS and development based on its API. My question may be simple to most so please help me in solving my problem.

I am trying to show a SimpleFillSymbol on a map but without any success. Can you help me in plotting the Symbol.

Perhaps I'm missing something, but it appears that you're passing a point to ring1 based on lat/long and then assigning a fill symbol to the point. By default, points don't have fill symbols. You'll need to buffer the point with a geometry service.

Also noticed you have conflicting css (tundra in your style tag, claro in your body class) which results in the red zoom slider.
