create static png chart using php

We need to create candlestick chart using PHP, with output to Static SVG/PNG format. The X axis will be date The Y axis will have multiple value : - ohlc candlestick - 8 line charts (for moving average) - 4 dot (to indicate a pointer) - trend line (a line, from specific x,y to x,y) the source data will be in mysql Prefer to use open source/free library (much better if you inform us the free lib you plan to use, via private message) so once php is executed, it will create a new png file in specific folder even better if it is in codeigniter.
