I have implemented a serial chart using AMCharts but have more columns than can be realistically shown in a window. To reduce the amount drawn, I have added a ChartsScrollBar which does the trick, but initially it selects all the data. Does anyone know how to set the initial zoom for the scroll bar?

I've written a JSFiddle to explain the problem - /

I'm trying to get the 'zoom bar' to show less than four item on startup.

You should listen fot "init" event and then use one of the available zoom methods. Here is modified fiddle: http://jsfiddle/Wd3GM/1/
