Google BarChart set width of bars?

I'm generating a BarChart with Google's javascript visualization libraries. I would like to make the bars in开发者_StackOverflow the chart to be wider than they currently are, but I can't find anything in the documentation which shows how to configure the width of the bars of each data set.

Any help?

Had this same question, figured I'd post for posterity. The bar.groupWidth appears to be the way to set this.

https://developers.google.com/chart/interactive/docs/gallery/barchart

For example:

 var options = {
        title: "Density of Precious Metals, in g/cm^3",
        width: 600,
        height: 400,
        bar: {groupWidth: "95%"},
        legend: { position: "none" },
      };
 var chart = new google.visualization.BarChart(document.getElementById("barchart_values"));
 chart.draw(view, options);

Try below format so the graph will have decently look, its not fixed but this solved our issue.

options: {
  titlePosition: "none",
  bar: { groupWidth: "50%" }
  // ...
}

data.push([" ", "t1","t2","t3","t4"]); // headings
data.push([" ", 0, 0, 0, 0]); // dummy bar so graph will display good
// push you actual data here
data.push([" ", 0, 0, 0, 0]); // dummy bar so graph will display good
