我有一个Google图表,需要将x轴(这是时间轴)的字体颜色更改为白色,以便与我的背景形成对比:
我尝试过
hAxis:{textStyle:{color:'#FFF'}
<DIV>
<p><U><font face="verdana" size="6" color="#CCCCCC">Thursday</font></U></p>
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<script type="text/javascript">
google.charts.load("current", {packages:["timeline"]});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var container = document.getElementById('example5.1');
var chart = new google.visualization.Timeline(container);
var dataTable = new google.visualization.DataTable();
dataTable.addColumn({ type: 'string', id: 'Federation' });
dataTable.addColumn({ type: 'string', id: 'Event' });
dataTable.addColumn({ type: 'date', id: 'Start' });
dataTable.addColumn({ type: 'date', id: 'End' });
dataTable.addRows([
[ 'WWE / NXT', 'AXXESS', new Date(0,0,0,18,0,0), new Date(0,0,0,22,0,0)],
[ 'WWN', 'Matt Riddles Bloodsport', new Date(0,0,0,15,0,0), new Date(0,0,0,18,0,0)],
[ 'WrestleCon', 'Wildkat Sports', new Date(0,0,0,18,0,0), new Date(0,0,0,21,0,0)],
[ 'WWN', 'Evolve', new Date(0,0,0,20,00,0), new Date(0,0,0,23,0,0)],
[ 'WrestleCon', 'WrestleCon Supershow', new Date(0,0,0,21,30,0), new Date(0,0,0,23,30,0)],
[ 'Knockout', 'Knockout in NOLA', new Date(0,0,0,17,00,0), new Date(0,0,0,20,00,0)],
[ 'ROH', 'RoH Supercard of Honor', new Date(0,0,0,19,30,0), new Date(0,0,0,22,30,0)],
[ 'WWN', 'Beyond Wrestling', new Date(0,0,0,20,55,0), new Date(0,0,0,23,55,0)]]);
var options = {
timeline: { colorByRowLabel: true },
tooltip: {isHtml: true},
legend: 'none',
backgroundColor: '#ffd'
};
chart.draw(dataTable, options);
}
</script>
<div id="example5.1" style="height: 300px;"></div>
</DIV>
答案 0 :(得分:5)
显然,hAxis.textStyle
不是可用的选项,
但是您可以在图表的'ready'
事件
一旦触发,找到svg <text>
元素并更改fill
颜色...
google.visualization.events.addListener(chart, 'ready', function () {
var labels = container.getElementsByTagName('text');
Array.prototype.forEach.call(labels, function(label) {
if (label.getAttribute('text-anchor') === 'middle') {
label.setAttribute('fill', '#ffffff');
}
});
});
请参阅以下工作片段...
google.charts.load('current', {
packages:['timeline']
}).then(function () {
var container = document.getElementById('example5.1');
var chart = new google.visualization.Timeline(container);
var dataTable = new google.visualization.DataTable();
dataTable.addColumn({ type: 'string', id: 'Federation' });
dataTable.addColumn({ type: 'string', id: 'Event' });
dataTable.addColumn({ type: 'date', id: 'Start' });
dataTable.addColumn({ type: 'date', id: 'End' });
dataTable.addRows([
[ 'WWE / NXT', 'AXXESS', new Date(0,0,0,18,0,0), new Date(0,0,0,22,0,0)],
[ 'WWN', 'Matt Riddles Bloodsport', new Date(0,0,0,15,0,0), new Date(0,0,0,18,0,0)],
[ 'WrestleCon', 'Wildkat Sports', new Date(0,0,0,18,0,0), new Date(0,0,0,21,0,0)],
[ 'WWN', 'Evolve', new Date(0,0,0,20,00,0), new Date(0,0,0,23,0,0)],
[ 'WrestleCon', 'WrestleCon Supershow', new Date(0,0,0,21,30,0), new Date(0,0,0,23,30,0)],
[ 'Knockout', 'Knockout in NOLA', new Date(0,0,0,17,00,0), new Date(0,0,0,20,00,0)],
[ 'ROH', 'RoH Supercard of Honor', new Date(0,0,0,19,30,0), new Date(0,0,0,22,30,0)],
[ 'WWN', 'Beyond Wrestling', new Date(0,0,0,20,55,0), new Date(0,0,0,23,55,0)]]);
var options = {
timeline: { colorByRowLabel: true },
tooltip: {isHtml: true},
legend: 'none',
backgroundColor: '#ffd',
};
google.visualization.events.addListener(chart, 'ready', function () {
var labels = container.getElementsByTagName('text');
Array.prototype.forEach.call(labels, function(label) {
if (label.getAttribute('text-anchor') === 'middle') {
label.setAttribute('fill', '#ffffff');
}
});
});
chart.draw(dataTable, options);
});
