Chart markers in C# and such...

Question

Hi,
Is there a method to create some drawing objects such as arrow, diamond etc... I'm using some charting soft where there is a limitations on number and size of such objects. There are very few basic chart markers such as arrow, diamond, triangle, dot that are too small and not resizable for some reason. Is there a way to create custom chart markers in C# that can be bigger and resizable please?
Thank you very much.
