Charts for stock analysis applications

I'm trying to build a stock analysis application and it uses 3 kinds of charts

• Area Charts
• Candlestick Charts
• Combination Charts

Currently i am doing this by using JQuery & Google charts and as u can see below its pretty awesome:

But now , i was annotations on these开发者_如何学Python charts . I've put up another question here on StackOverflow asking if something can be annotated on Google charts .

But here , i'm asking if there are any other charts that i can use which supports these 3 types of charts AND allows me to annotate (draw shapes at positions) on them.

please help :( I have to deliver this in a week !

I would really recommend HighCharts. They are free for open source project bur requires a license if you use it in a commercial project. They even have a library dedicated to stocking charts, called HighStock.

If you want a free library, my recommendation is Flot. However, it does not come with as many different chart types as HighCharts.

I think you can use jQPlot

if you are using a server side language there is plenty of libraries that you can use and draw images and of course it can be a chart, also there are some Libraries specifically for drawing Charts.

But here are some really good JavaScript chart Solutions

HighCharts Offer a free licence for non-commercial use, based on jQuery
GRaphael MIT Licence , based on the famous raphael library
Flot With less interaction but still free
JSCharts A non-free alternative

The Good point about JS is that it can be interactive.
