以下示例来自 Google 使用 Google Charts 创建 ColumnChart
function drawVisualization() {
// Create and populate the data table.
var data = google.visualization.arrayToDataTable([
['Year', 'Austria', 'Belgium', 'Czech Republic', 'Finland', 'France', 'Germany'],
['2003', 1336060, 3817614, 974066, 1104797, 6651824, 15727003],
['2004', 1538156, 3968305, 928875, 1151983, 5940129, 17356071],
['2005', 1576579, 4063225, 1063414, 1156441, 5714009, 16716049],
['2006', 1600652, 4604684, 940478, 1167979, 6190532, 18542843],
['2007', 1968113, 4013653, 1037079, 1207029, 6420270, 19564053],
['2008', 1901067, 6792087, 1037327, 1284795, 6240921, 19830493]
]);
// 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"
}
});
}
效果很好,但是,我只想要每列一个值,所以我将其更改为:
function drawVisualization() {
// Create and populate the data table.
var data = google.visualization.arrayToDataTable([
['Month', 'How many'],
['07', 193],
['08', 114],
['09', 158]
]);
// 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"
}
});
}
现在垂直轴不是从 0 开始,而是接近最低值,在这种情况下是 114 - 这是一个错误吗?我仍然希望它从 0 开始显示,因为像这样快速浏览它非常令人困惑
有任何想法吗?
