我有一个基本的谷歌图表:-
function drawVisualization() {
// Create and populate the data table.
var data = google.visualization.arrayToDataTable([
['Year', 'Austria', 'Belgium', 'Czech Republic'],
['2006', 1600652, 4604684, 940478],
['2007', 1968113, 4013653, 1037079],
['2008', 1901067, 6792087, 1037327]
]);
// Create and draw the visualization.
new google.visualization.ColumnChart(document.getElementById('visualization')).
draw(data,
{title:"Yearly Coffee Consumption by Country",
width:600, height:400,
hAxis: {title: "Year"}}
);
}
我希望能够指定边框颜色和宽度等。你能告诉我如何使用API命令:-backgroundColor.stroke,backgroundColor.strokeWidth,
即如何添加这些 API 调用。
谢谢
