I'm happy with NDataZoomTool , but I want also to be able to do the following

1. Is it possible to combine NDataZoomTool + NOffsetTool(or in another way), so I want to be able to zoom in data and at the same time move screen to select data which are close to current selected subset

2. When I have NDataZoomTool , I want to be able dig in data using mouse wheel (when I move wheel down, it will behave as if I selected smaller area with NDataZoomTool and moving wheel up will move me step back showing previous subset of data)

3. I want to show current selected subset of data (like small chart in additional window where I show data "" + selected area)

Thanks in advance!

Hello.
I'm also interesting in Alex's question number 1. But I want to know how to do the same thing in code. In more detail: I have on my chart NSelectorTool, NAxisScrollTool, NDataPanTool, NDataZoomTool. So the user have the ability to change the scale. I know the line series and the point index on this line series. I want to put this point in the center of the chart without changing the scale.
