我创建了一个谷歌区域图表,并给出了一个5的pointSize作为我的截图。
有没有办法为我的点添加笔画,如下图所示。

是的,但这很棘手。
只需创建一个脚本,即可找到在<circle>
内创建的svg
中的所有div
元素。
对于所有这些圈子,找到stroke
属性并将其设置为您想要的任何颜色(示例中为#000000
),并将stroke-width
属性设置为您想要的任何线宽(对于折线图,Google Visualization的默认值为2
。
禁用图表交互,使其保持这种状态。
让我们从一些简单的代码开始:
function drawVisualization() {
// Some raw data (not necessarily accurate)
var data = google.visualization.arrayToDataTable([
['Series ID', 'Value'],
['A', 165],
['B', 135],
['C', 157],
['D', 139],
['E', 136]
]);
// Create and draw the visualization.
var ac = new google.visualization.AreaChart(document.getElementById('visualization'));
ac.draw(data, {
isStacked: true,
width: 600,
height: 400,
pointSize: 10
});
}
这看起来像这样:
Google Visualizations在可视化div
元素中使用以下通用代码结构呈现此对象:
<div id="visualization" style="width: 600px; height: 400px; position: relative;">
<div style="position: relative; width: 600px; height: 400px;" dir="ltr">

这是很多东西,但总的来说,它的工作方式是:
div
(&#39;可视化&#39;在这种情况下)div
svg
元素 svg
元素本身通常遵循以下模式:
svg
根据您的图表,变化略有不同(如果您不包含标签,则可能无法生成&#39;标题&#39;组,一般情况下,如果更改库,方式它呈现的图表会略有不同。但是,对于“核心图表”包,通常一切都将遵循上述内容。
由于你想摆弄实际的图表区域部分(图中的圆圈),让我们更仔细地查看该元素。以下是该组的svg
。

这个显示:
因此我们希望专注于E组。以下是圈子的代码:

<circle cx="208" cy="157.45" r="6" stroke="none" stroke-width="0" fill="#3366cc">

<circle cx="485.5" cy="156.22" r="6" stroke="none" stroke-width="0" fill="#3366cc">
</g>
最简单的方法就是改变&#34;中风&#34;元件。
例如,如果我手动将笔触宽度更改为2(与线宽相同),并将颜色更改为黑色(如示例所示),我会得到:
<g>
<circle cx="115.5" cy="120.55000000000001" r="6" stroke="#000000" stroke-width="2" fill="#3366cc">
<circle cx="208" cy="157.45" r="6" stroke="#000000" stroke-width="2" fill="#3366cc">
<circle cx="300.5" cy="130.39000000000001" r="6" stroke="#000000" stroke-width="2" fill="#3366cc">
<circle cx="393" cy="152.53" r="6" stroke="#000000" stroke-width="2" fill="#3366cc">
<circle cx="485.5" cy="156.22" r="6" stroke="#000000" stroke-width="2" fill="#3366cc">
</g>
这是它的样子:
但这种方法存在一些问题。每当您将鼠标悬停在图表上时,它会重新绘制SVG元素(因为它会突出显示所单击的任何圆圈,或者如果单击图例则突出显示所有圆圈),并且会变为如下所示:
<g>
<circle cx="393" cy="152.53" r="8" stroke="#3366cc" stroke-width="1" fill="#ffffff">
<circle cx="393" cy="152.53" r="6" stroke="none" stroke-width="0" fill="#3366cc">
</g>
所以它只是围绕它重新绘制一个更大的圆圈,但这意味着你的花哨格式已经全部消失了!
基本上,你需要禁用交互性,或创建一个即使有另外一个圆圈也可以运行的脚本(因为你不希望两个圆圈最终都有黑色圆圈,因为它会超大而丑陋)。
所以我建议的是寻找半径为X的圆圈(其中X是页面上大多数圆圈的任意一个,与较小的数字相关联),并存储所有这些元素在数组中。然后只需浏览数组,在图表与之交互时更改stroke-width
和stroke-color
属性。
意识到这会变得更加复杂,因为你正在为所有圈子动态地执行此操作。如果图表中有任何其他圆圈,他们将得到相同的处理,或搞砸数学。哪个会很糟糕。
答案 1 :(得分:1)
这是一个简单的解决方案。每个点的样式都是以编程方式定义的。这是通过向具有角色&#39;样式的数据表添加一列来完成的,然后使用简单的循环将该样式添加到所有点。试试JSFiddle:https://jsfiddle.net/m45z7mmp/
google.setOnLoadCallback(drawChart);
function drawChart() {
var dataArray = [
['X', 'Y', {
'type': 'string',
'role': 'style'
}],
[1, 3],
[2, 2.5],
[3, 3],
[4, 4],
];
for (i = 1; i < dataArray.length; i++) {
dataArray[i].push('point {stroke-width: 2; stroke-color: #e97b2c; fill-color: #eeeeee }');
}
var data = google.visualization.arrayToDataTable(dataArray);
var options = {
colors: ['#e97b2c'],
pointSize: 8,
};
var chart = new google.visualization.AreaChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
