You have a few options:

• http://www.achartengine.org/

• http://code.google.com/p/chartdroid/

• http://www.artfulbits.com/products/android/aiCharts.aspx (commercial)

• http://code.google.com/apis/chart/ (online only)

The first one for sure has zoom capabilities. I don't know about multitouch, though.

The google API has some interaction built-in and you could take advantage that it runs in a WebView, so you can use its own zoom capabilities. Since your app is going to require a network connection anyway, it seems like a reasonable option.

AChartEngine does support multi-touch / pinch zoom. You can add / remove data to / from your datasets and then call chartView.repaint() and you will get a dynamic behavior.
