Multi-band bubble chart

This demo shows how to a simple "plugin" can be used to arrange each subsequent data point into a separate "band" of values.

It uses AmCharts.addInitHandler() method to execute custom code before the chart is instantiated.

Our custom function there goes through data, and adjusts actual values so that each subsequent data point is shifted by certain value step. (as set in custom parameter bandValueScrope)

It also sets labelFunction for the vertical value axis to show recalculated values on axis labels as well.

Finally, it also checks if the axis has any guides attached to it. It then assumes those guides are band indicators and adjusts their value and toValue accordingly.
