VaadinVisualizations Chart Manipulation

Good morning,

First of all, being this my first post in 2 years working with Vaadin, let me congratulate the people developing it. Nice job.

In my project, with Vaadin 6, I use LineCharts to sample data (VaadinVisualizations2.1). One of the requirements states the need of manipulating the vertical axis of the chart. I mean, instead of the original min/max interval of the vertical axis, it should allow the user to select it, kind of a vertical zoom.

In the Google Charts API it states configuration options for that - vAxis.maxValue or vAxis.minValue. I’ve tried to use them with the method .setOption()… But with no success.

Anyone can help me with this issue?
