I am looking for a way to update one and only one value in a dojox chart2d. There is a way to update an entire series, which involves

mychart.updateSeries("myseriesname",array_of_data)
mychart.render()

but This is too slow for my application.

What I want to do is be able to drag the mouse over a vertical bar chart and have the values change as I am doing it. Only one or two values will need to change, so there is no need to reload all of the plots, just the two or three values that are changing.

Is there a method that will quickly update only one or two values without lag?

Thanks, Nick O

I may just end up writing my own css version :S
