In your original code, the circle and the arrows are both drawn at the top-right corner. The circle overdrawn the arrow, so the arrow is not visible. In my test code above, I move the arrow to the top-left corner.
The circle symbol is supported since ChartDirector 5.1. The CDML arrow symbol is only supported in recent versions of ChartDirector.
Please try my code above. It just draw an empty chart with a title displaying the ChartDirector version and the arrow and circle symbols. Please let me know if it works in your case.
If the code above works, but it does not work in your code, is it possible create a complete example that I can try so I can reproduce the problem? There are many reasons why the symbols are not displayed. For example, the ChartDirector version may be too old, or there may be other things at the same position covering the symbols. With the complete code, we can see how your chart is configured.
