Draw candlestick in Envision

[Shi Yi]

How can I draw the candlestick chart in envision?

I find the flotr2 adapter in envision. So I suppose it is possible to do anything in envision that can be done in flotr2.

Are there any existing methods that I can draw candlestick or should I write a plugin for it?

If I need to write a plugin for it myself, could you give me some guidance?

Thank you so much for you help.

You need to 'hack' the library a little bit. Search envision.js for line started like this: Flotr.addType(...). You would probably see there's no addType 'candles'. What I did was just copy function Flotr.addType('candles', ...) from flotr2.js to envision.js. Here is all the code you need to paste to your envision.js library: http://jsfiddle.net/zhgRM/

If everything is OK you should be able to use it like this in your envision config:

...

'lite-lines': { show: false },
candles : { show : true, candleWidth : 0.6 },

...

I hope it's not too late.
