Hello All,

I have five columns in database, open,high,low,close,time. I want to create a real time candlestick chart that takes time from database and shows it on the x axis (axis of the abscissas) and also shows the open, high, low and close values at that particular time on the y-axis (axis of ordinates). The chart would also have to update itself every 2 seconds. How can this be achieved?

Please help.

Thanks in Adavance!
