它使用了一个聪明的黑客组合图完成我想要的。

  google.load（visualization，1 ，{packages：[corechart]}）; 
 google.setOnLoadCallback（drawChart）; 

 function drawChart（）{
 var data = new google.visualization.DataTable（）; 
 data.addColumn（'string'，'Name'）; 
 data.addColumn（'number'，'Value'）; 
 data.addColumn（{type：'string'，role：'annotation'}）; 

 data.addRows（[
 ['Foo'，53，'Foo text']，
 ['Bar'，71，'Bar text']，
 ['Baz'，36，'Baz text']，
 ['Cad'，42，'Cad text']，
 ['Qud'，87，'Qud text']，
 ['Pif'，64，'Pif text'] 
]）; 

 var view = new google.visualization.DataView（data）; 
 view.setColumns（[0，1，1，2]）; 

 var chart = new google.visualization.ComboChart（document.getElementById（'chart_div'））; 

 chart.draw（view，{
 height：400，
 width：600，
 series：{
 0：{
 type ：'bars'
}，
 1：{
 type：'line'，
 color：'gray'，
 lineWidth：0，
 pointSize ：0，
 visibleInLegend：false 
} 
}，
 vAxis：{
 maxValue：100 
} 
} 
} 
 

I am using Google Chart API to create chart for values which goes from 1 to millions.

Problem The bars which are representing smaller values (ex: less than 50 or so) are invisible on graph and no way I can see what values correspond to certain x-axis.

This would be solved if I can somehow print y-axis values on top of bars.But, I couldn't find any mention in the API doc on how to do it.

There is similar problem here, but it doesn't answers my question.

put labels on top of inside bar in google interactive bar chart

There are some other more than year old unanswered questions here, I am hoping someone might have found a solution or a workaround by now, that is why asking this question again.

It uses a clever hack of a combo chart to accomplish what I think you're looking for.

google.load("visualization", "1", {packages: ["corechart"]});
google.setOnLoadCallback(drawChart);

function drawChart() {
  var data = new google.visualization.DataTable();
  data.addColumn('string', 'Name');
  data.addColumn('number', 'Value');
  data.addColumn({type: 'string', role: 'annotation'});

  data.addRows([
    ['Foo', 53, 'Foo text'],
    ['Bar', 71, 'Bar text'],
    ['Baz', 36, 'Baz text'],
    ['Cad', 42, 'Cad text'],
    ['Qud', 87, 'Qud text'],
    ['Pif', 64, 'Pif text']
  ]);

  var view = new google.visualization.DataView(data);
  view.setColumns([0, 1, 1, 2]);

  var chart = new google.visualization.ComboChart(document.getElementById('chart_div'));

  chart.draw(view, {
    height: 400,
    width: 600,
    series: {
      0: {
        type: 'bars'
      },
      1: {
        type: 'line',
        color: 'grey',
        lineWidth: 0,
        pointSize: 0,
        visibleInLegend: false
      }
    },
    vAxis: {
      maxValue: 100
    }
  });
}
