OutOfMemoryException from Chart Control

[Dan Searle]

My application uses a chart control to display some data and it sometimes gives an OutOfMemoryException.

One case I've seen this is when my application is trying to draw a single series with 27 points (all of which are the same).

Below is the stack from the error, any help would be appreciated.

System.OutOfMemoryException: Out of memory.
