Set the "view" parameter of the ScatterChart's ChartWrapper object. It
takes a "columns" parameter, which is an array of columns (exactly like the
DataView#setColumns method):
var myChart = new google.visualization.ChartWrapper({
// set chartType, containerId, options, etc,
view: {
columns: [0, 1, 2, 3] // use columns 0-3 for this chart
}
});
