C++ graph implementations

Hi, I'm looking for someone who could implement (among other things) trendline calculations for me. I know ProRealTime is written in Java, and has "ProRealTrend", but I don't know if this is calculated on the server or in the client. If that would be in the client you might glance how they do it & implement it in the target language (C++). The purpose is that I give you a list of timestamp/open/close/high/low/volume CSV file and you give me a graph (for example use ChartDirector -- i use the financial graphing features there) with the trendlines drawn. I also do have some other code I downloaded for different programs which could be implemented, but I think the best bet would be the ProRealTrend feature mentioned above. So as a start this would be a fixed price project for the trendline drawing, and afterwards continue as an hourly project for the other indicators I have in mind. Rules: - available on gtalk during the course of this project - budget is fake (obviously), please estimate according to planned work.
