@SciChart: I like your chart for scientific charting but like StockChart SL from Modulus more for financial apps. It looks like finance is their niche. Based on the trial versions that I've seen it's pretty good performance and tons of finance related features. It looks like the price has come down to $500 also. But again your chart is better for science stuff. My company has a license for both your chart and the Modulus StockChart SL chart. We use both.
