I'm considering to develop a visualization tool, in which the candle stick plot is a big part. I've seen people doing this using Python's matplotlib, Qt and PyQt. There are also several tools out there helping to draw financial plots. I'm now a bit lost, can anyone kindly give me some suggestions about which tool to use? Other requirements: the plot needs to be dynamic, and can zoom in/out. Also, my programming skill is limited, C++ should be avoided in the case Python can solve the problem well enough. Thanks in advance!

To answer my own question. Lately I found the HighStock, which is in JavaScript.
