[英]Customizing Google Material bar Chart
我必須制作一張如圖所示的圖表,它看起來幾乎類似於Google的Material條形圖,但需要進行一些修改。 到目前為止,我還沒有找到一種方法來修改懸停時的顏色,刻度號或線數以及圖表區域的寬度。 有人能幫我嗎 ?
google.charts.load('current', {'packages':['corechart','bar']}); google.charts.setOnLoadCallback(barChart); function barChart() { var data = new google.visualization.arrayToDataTable([ ['Opening Move', 'Percentage', { role: 'style' }], ["King's pawn (e4)", 44, ' ' ], ["Queen's pawn (d4)", 31, ''], ["Knight to King 3 (Nf3)", 12,''], ["Queen's bishop pawn (c4)", 10,''], ['Other', 3, ''] ]); var options = { width: 520, height: 320, legend: { position: 'none' }, bars: 'horizontal', axes: { x: { 0: { side: 'top', label: 'Percentage', } } }, hAxis: { ticks: [10,20,30] }, bar: { groupWidth: "90%" }, // chartArea: { // width: '78%', // left: '22%' // }, colors:['#c6dbfd','#c6dbfd','#c6dbfd','#c6dbfd','#c6dbfd','#c6dbfd'] }; var chart = new google.charts.Bar(document.getElementById('bar-chart')); chart.draw(data, options); }

您正在使用“材料條形圖”,目前它具有非常有限的一組功能(如此處和此處所示 )。
這解釋了為什么報價和圖表區域不起作用。 我創建了一個帶有非材料版本的小提琴: https : //jsfiddle.net/5Lnbbbbw/1/ 。
它是相似的,但是使用:
var chart = new google.visualization.BarChart(document.getElementById('bar-chart'));
代替
var chart = new google.charts.Bar(document.getElementById('bar-chart'));
現在進行懸停:這很困難,因為沒有選項可以管理它。 實際上,您在鼠標懸停和點擊時所看到的就是添加到圖表中的新元素。 它不是通過CSS管理的。
但是,您可以這樣做:
#bar-chart svg g[clip-path] g:not(:first-child) rect:hover {
fill: blue;
stroke: black;
stroke-width: 1;
}
圖表區域是具有clip-path
屬性的svg元素g
。 第一個子項將所有刻度線(垂直線)分組,因此我們不想為其添加css屬性。
請注意,如果刪除刻度線,則可能必須稍微更新css。
如果您想了解更多關於bar的css選項的信息,可以在這里找到更多信息。
我發現此Codepen使用jQuery在圖表上的條形圖中添加了一定百分比。 也許會有所幫助嗎?
