Sencha Charts Extending Columns outside of the view port

Question

I'm working on getting familiar with Sencha charts. I'd like to know if there is any way that I can extend a column outside of the view port. For example I have data for which I have the min, first quartile, third quartile, and max for and I make a stacked chart out of these. However the max contains several outliers that probably won't be relevant to the user. What I want to do is end the view after the third quartile somewhere. Is there a simple and easy way to accomplish this?

how about taking outliers out of the data set? – dbrin Dec 21 '12 at 06:38 — dbrin, Dec 21 '12 at 06:38
That would be nice to do but not what I want to do. – Chris Maness Dec 21 '12 at 14:30 — Chris Maness, Dec 21 '12 at 14:30

You would have to work out the algorithm to get the percentage of records that go beyond your third quartile. That shouldn't be too hard.

Then create a function that set's the chart's width to a size which is equal to:

[viewport width] * (1 + [the percentage])

You can use the chart's setWidth method for this.

You can call this function in the chart's beforerefresh event (it should fire after the chart store data is loaded but before it is rendered on the chart) and also in the viewport's resize event.
