I developed my own backtesting software in C# from scratch as I was not satisfied with limitations of the various commercial packages available. So far all it generates however are CSV files of the results. What I would like to do is chart these and show the entries/exits similar to the way backtesting works natively in NinjaTrader. Does anyone know of a good (preferably free) stock charting class that I can download to accomplish this easily? So far the ones I have found googling are pretty lacking.

Some ideas here:

Nuclear Phynance

If its uncool to post links to other forums let me know and I'll change the post.

Maybe GnuPlot, it's free, easy, and powerful.

I guess the main feature I am looking for is the ability to pan and zoom. Generating a static chart is not too difficult but for the length of time I am backtesting, its impossible to see any detail without zooming in.

I've used ChartDirector in the past, it's pretty cool, and you can implement zoom/pan
See ChartDirector Chart Gallery - Finance Charts

Only limitation of the trial version is that you get a "Created with ChartDirector" on the chart.

I've included the demo app I just compiled. Launch CSharpChartExplorer.exe

For financial charts, choose ... financial charts, and for zooming/scrolling, choose ... zooming and scrolling :-)

Perfect! Exactly what I was looking for. Thanks gomi!

If you want to program your charts yourself (I do as third party software is sometime buggy) then I can recommend the Chart Controls for the .NET framework from Microsoft: archive.msdn.microsoft.com/mschart

The link contains a download-sample of different charts and how the source-code looks. Very easy to understand. The download contains an exe file you can run so you don't have to compile anything to get the sample running

I think the best way is using R The R Project for Statistical Computing with RStudio and the financial analytics package, so you can print all the statistics too.
