谷歌圖表 - Material 柱形圖

以下是一個 material 柱形圖的示例。我們已經在谷歌圖表配置語法一章中看到用於繪製此圖的配置。那麼，讓我們來看完整的示例。

配置

我們使用 Bar 類來顯示 material 圖表。

//classic chart
var chart = new google.visualization.ColumnChart(document.getElementById('container'));

//Material chart
var chart = new google.charts.Bar(document.getElementById('container'));

            var options = {title: 'Population (in millions)'};  

            // Instantiate and draw the chart.
            var chart = new google.charts.Bar(document.getElementById('container'));
            chart.draw(data, options);
         }
