What is bar chart?

  • A bar chart or bar graph is a chart or graph that presents grouped data with rectangular bars with lengths proportional to the values that they represent.
  • The bars can be plotted vertically or horizontally.

Configurations:

We've used role as annotation configuration to show data labels in bar chart.

var data = google.visualization.arrayToDataTable([
   ['Year', 'Asia', { role: 'annotation'} ,'Europe', { role: 'annotation'}],
   ['2012',  900,'900',      390, '390']
]);
