i'm currently working with d3.js and with the nvd3 library, i need a chart that has multiple bars that can be stacked and grouped like this example http://nvd3.org/ghpages/multiBar.html plus a line chart like the following example http://nvd3.org/ghpages/linePlusBar.html
So what I need exactly is a MultiBarChart with a line chart , can anyone show me an example somewhere. Thanks
