Guys,

I didn't find any existing functionality in current charts. We need to draw bars from the specific position (y value). Is it possible?

For ex:
y
| []
| [] []
| [] []
x|____[]_________________

Lines (bars)

We need to be done as in attachment.

Hi,

That functionality does not currently exist in ExtJS. You'd have to write a custom Series to handle it, extending Column would be a good start.

At EdgeUX (http://edgeux.com)we love financial charting and are just about to release a commercial Candlestick chart extension as well as other charting extensions in the pipeline. All of which will be available on our website (http://edgeux.com).

What you are suggesting could be thought of as a simplified candlestick. It wouldn't take much for us to add the chart you are suggesting into our release. Feel free to contact us if this is something you'd be interested in.

I think i've found a solution: just make a stacked bar chart and set the opacity of first element in each chart to zero :) :) :)

That's a good workaround. Nice thinking!
