我希望this Google LineChart看起来更像this chart from GitHub。我正在重新创建GitHub的图表,因为我想要一个高质量的版本(矢量),而不是一个高度压缩的JPEG(他们正确的想法,无论如何都将图表保存为JPEG格式。)。
我想将图例移动到图表中并添加垂直网格线(在水平轴上“年”)。有谁知道如何做到这一点?
以下是代码,但请随时修改my JSFiddle:
google.load('visualization', '1', {packages: ['corechart', 'line']});
google.setOnLoadCallback(function() {
var data = google.visualization.arrayToDataTable([
['Year', 'JavaScript', 'Java', 'Ruby', 'PHP', 'Python', 'CSS', 'C++', 'Objective C', 'C', 'C#', 'Perl', 'Emacs Lisp', 'VimL', 'Shell','HTML'],
['2008', 2, 7, 1, 4, 3, null, 8, 9, 5, null, 6, null, null, null, null],
['2009', 2, 7, 1, 4, 3, null, 8, 9, 6, null, 5, 10, null, null, null],
['2010', 2, 5, 1, 4, 3, null, 8, 9, 6, null, 7, null, 10, null, null],
['2011', 2, 5, 1, 4, 3, null, 7, 8, 6, 10, 9, null, null, null, null],
['2012', 2, 3, 1, 4, 5, null, 7, 8, 6, 9, null, null, null, 10, null],
['2013', 1, 3, 2, 4, 5, 10, 7, 8, 6, 9, null, null, null, null, null],
['2014', 1, 2, 3, 4, 5, 6, 7, 9, 8, 10, null, null, null, null, null],
['2015', 1, 2, 3, 4, 5, 6, 7, null, 9, 8, null, null, null, null, 10]
]);
var options = {
title: 'Rank of top languages on GitHub over time',
width: '100%',
height: 600,
hAxis: {
title: 'Time',
},
vAxis: {
title: 'Rank',
viewWindow: {
min: 1
},
direction: -1,
gridlines: {
count: 11
}
}
};
var chart = new google.visualization.LineChart(document.getElementById('chart'));
chart.draw(data, options);
});

更改数据类型 - >输入:'date'
google.load('visualization', '1.1', {packages: ['corechart', 'line']});
google.setOnLoadCallback(function() {
var data = google.visualization.arrayToDataTable([
[{label: 'Year', type: 'date'}, 'JavaScript', 'Java', 'Ruby', 'PHP', 'Python', 'CSS', 'C++', 'Objective C', 'C', 'C#', 'Perl', 'Emacs Lisp', 'VimL', 'Shell','HTML'],
[new Date(2008, 0, 0), 2, 7, 1, 4, 3, null, 8, 9, 5, null, 6, null, null, null, null],
[new Date(2009, 0, 0), 2, 7, 1, 4, 3, null, 8, 9, 6, null, 5, 10, null, null, null],
[new Date(2010, 0, 0), 2, 5, 1, 4, 3, null, 8, 9, 6, null, 7, null, 10, null, null],

var options = {
