[英]Highcharts Gauge
我正在使用highcharts,我想展示一個大規格(500x500px)。 調整儀表的大小非常簡單,但是具有值的小塊不會調整大小。 如何讓那個小塊更大?
謝謝您的幫助!
jsFiddle: http : //jsfiddle.net/AVd8k/
$(function () {
$('#container').highcharts({
chart: {
type: 'gauge',
plotBackgroundColor: null,
plotBackgroundImage: null,
plotBorderWidth: 0,
plotShadow: false,
width: 500,
height: 500
},
title: {
text: 'Speedometer'
},
pane: {
startAngle: -150,
endAngle: 150,
background: [{
backgroundColor: {
linearGradient: { x1: 0, y1: 0, x2: 0, y2: 1 },
stops: [
[0, '#FFF'],
[1, '#333']
]
},
borderWidth: 0,
outerRadius: '109%'
}, {
backgroundColor: {
linearGradient: { x1: 0, y1: 0, x2: 0, y2: 1 },
stops: [
[0, '#333'],
[1, '#FFF']
]
},
borderWidth: 1,
outerRadius: '107%'
}, {
// default background
}, {
backgroundColor: '#DDD',
borderWidth: 0,
outerRadius: '105%',
innerRadius: '103%'
}]
},
// the value axis
yAxis: {
min: 0,
max: 200,
minorTickInterval: 'auto',
minorTickWidth: 1,
minorTickLength: 10,
minorTickPosition: 'inside',
minorTickColor: '#666',
tickPixelInterval: 30,
tickWidth: 2,
tickPosition: 'inside',
tickLength: 10,
tickColor: '#666',
labels: {
step: 2,
rotation: 'auto'
},
title: {
text: 'km/h'
},
plotBands: [{
from: 0,
to: 120,
color: '#55BF3B' // green
}, {
from: 120,
to: 160,
color: '#DDDF0D' // yellow
}, {
from: 160,
to: 200,
color: '#DF5353' // red
}]
},
series: [{
name: 'Speed',
data: [80],
tooltip: {
valueSuffix: ' km/h'
}
}]
},
// Add some life
function (chart) {
if (!chart.renderer.forExport) {
setInterval(function () {
var point = chart.series[0].points[0],
newVal,
inc = Math.round((Math.random() - 0.5) * 20);
newVal = point.y + inc;
if (newVal < 0 || newVal > 200) {
newVal = point.y - inc;
}
point.update(newVal);
}, 3000);
}
});
});
通過替換series
(整個對象)來嘗試這個:
series: [{
name: 'Speed',
data: [80],
tooltip: {
valueSuffix: ' km/h'
},
dataLabels: {
enabled: true,
style: {
//fontWeight:'bold',
fontSize: '22px'
}
}
}]

當然,您可以根據需要調整字體大小
看起來你所追求的屬性是:plotOptions.gauge.dataLabels.style.fontSize
http://api.highcharts.com/highcharts#plotOptions.gauge.dataLabels.style
嘗試在選項中添加以下內容:
plotOptions: {
gauge: {
dataLabels: {
style: {
fontSize: '60px'
}
}
}
}
您可能需要使用x和y屬性重新定位它。
