我正在使用带有注释的谷歌api折线图.如何更改字体大小和字体格式？
<script type="text/javascript">
google.load("visualization","1",{packages: ["corechart"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('string','');
data.addColumn({type: 'string',role: 'annotation'});
data.addColumn('number','');
data.addRows([['2010','67',67]]);
data.addRows([['2011','69',69]]);
data.addRows([['2012','68',68]]);
data.addRows([['2013',67]]);
var options = {
width: 350,height: 250,pointSize: 5,legend: {position: 'none'},chartArea: {
left: 0,top: 60,width: 300,height: 75},vAxis: {
baselineColor: '#fff',gridlines: {color: '#fff'},minValue: 64,maxValue: 71
},tooltip: {trigger: 'none'},enableInteractivity: false,annotation: {
1: {
style: 'default'
}
},series: {0: {color: '#4D7AD3'},1: {color: '#4D7AD3'}}
};
var chart = new google.visualization.LineChart(document.getElementById('chart_div'));
chart.draw(data,options);
}
</script>
<body>
<h2>Line Charts</h2>
<div id="chart_div"></div>
</body>
解决方法
试试这个
var options = {
annotations: {
textStyle: {
fontName: 'Times-Roman',fontSize: 18,bold: true,italic: true,color: '#871b47',// The color of the text.
auraColor: '#d799ae',// The color of the text outline.
opacity: 0.8 // The transparency of the text.
}
}
};
