It's really easy to create such graphic i WPF, no need for 3rd parties imho.
And the best thing... you get exactly what you need :D

I can recommend http://www.apress.com/9781430224815 , very good book and after I read the interesting chapters for me it was very easy to understand the simplicity in charting.

Hi again...

Please take a look what I developed in less than 10 hours.

I do have a lot of programming experience, but never touched WPF until I bought that book :cool:

Yahh..... I do like your UI, looks very promising.

Dear Janus007,

Thank you for your post. My chart is from third party called Devexpress. They have a issue on the charting thing since they assume clients use chart to display data and once you have some Live Data like forex quote, it is kind of hard to update the candlestick. Usually, when new price update comes, we only need to update very last candle instead of whole chart of hundreds candles. But Devexpress only allows update whole thing together. It really annoys me. Now my chart is like a static one which means i have to press update button to redraw whole thing if I wanna see the updated chart.

My Question: Whether your WPF chart could implement following function: When the live forex price came, you could see only last candle is being updated Live instead of whole chart of candles:) THanks!

My experience with charting from the WPF Toolkit is that it's easy to use, but suffers from very poor performance, especially for large datasets.

I explored it some time ago for financial charting and decided not to use it because of its poor performance.

Although I never used wpf to do anything before, however, I really heard something like this. And the learning curve is kind of steep. I currently have no passion to learn that:)

My chart is graphic and needs manual update by clicking button when you wanna see current condition.

Yes it should be doable.... however this was just a small demo/ prototype to explore what I could develop in a reasonable timeframe.

WPF is hard to tweak for performance, especially when there are many objects that has to be redrawn, but it can be done :cool: Other developers has experienced similar issues when working with a bunch a objects in the canvas , i.e. : http://khason.net/blog/how-to-high-performance-graphics-in-wpf/

Thank you very much for the link. I will read through that.

Janus, I noticed that you were active in the TickZOOM thread. I am just curious about what kind of trading system or software are you using now?

The performance issues I speak of are not regarding WPF, but the charting control itself.

I used it in both its WinForms life as well as WPF and its performance is poor compared to other controls out there.
