Charts issue

Hi,

I have an HTML view,where i have created 2 iframes.In the 1st Iframe i have placed one bar chart and in 2nd iframe another bar chart.
By using openURL iam trying to access the HTML view in the form.While accessing the application its showing the 2 IFRAMES along with the tabs.But i dont want the tabs.I need only 2 bar charts to display.

Please help me out of this.
