GreatCharts is used for creating good-lookings stock charts. It was mainly developed for stock Web sites, to create on-the-fly charts. Small charts (closing+volume) can be drawn in less than 10ms. It can read different input formats, and can draw up to 20 charts in one PNG with different scales. The supported types are: Closing, OHLC, Volume, and Candlestick. The supported formulas are: Moving, Moving Average, RSI, MACD, and Stochastic. The supported drawing types are: line, filled, bar, and filled bars (filled can be transparant to the background/underlaying plots). Everything is configurable through a config file and parameters, including your own background, sizes, etc.
