Dynamic report in windows application vs2008

Dear all:

I am developing a win app which process and generate data dynamically. I want to use the Microsoft reportviewer to analyse the generated data. I have a few problems about the report.

Firstly, can I manage the report dynamically? Can I access the report items like matrix, chart programmatically? Can I bound the datasource dynamically?

Second, I was playing around the chart in report. When I drag a data field to the value column ie the y axis, the value is defined as eg count(field!object.x) by default. And then I drag another one to the category column, ie the x axis, then compile. The chart is displayed correctly. However, I want to display the value of field!object.x. So I change it to value=field!object.x. But the chart is not displayed correctly. If x=0.5, for instance, it is displayed as 0on the chart.

The last question is also a general one. What is a good way to make a report about the data generated at run time? I mean without a database such as SQL etc.

Thanks
