刷新 TabActivity 的 Tab 内容

Question

I have a tab with an intent as its content:

    tabHost.addTab(tabHost.newTabSpec("tab3")
            .setIndicator("Chart")              
            .setContent(lineChartIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)));  

How is it possible to refresh the content of a tab? I am thinking of a method like

tab.refreshContent()

or similar. Background is: My intent contains a graph and I want to repaint this graph upon click of a button while the tab remains selected. Thanks.
