The documentation needs a lot of work; ChartWrappers are just one of a number of insufficiently documented features. The ChartWrapper constructor takes an object with the parameters "containerId" (the id of the container to put the chart in), "chartType" (the type of chart to draw), "dataTable" (the DataTable or DataView object to use to draw the chart, leave out when using a Dashboard), "dataSourceUrl" (a url to query if using a remote data source), "options" (an object of options for the chart), "state" (an object describing the initial state of the chart), and "view" (an object describing the DataView to use when drawing the chart).
The "view" parameter takes an object with "rows" (an array of row indices to use when drawing the chart, analogous to the DataView#setRows<https://developers.google.com/chart/interactive/docs/reference#DataView_setRows>method) and "columns" (an array of column indices or objects to use when drawing the chart, analogous to the DataView#setColumns<https://developers.google.com/chart/interactive/docs/reference#DataView_setColumns>method) parameters.
