[英]Draw vertical lines and horizontal bands
我直接將數組繪制到我的高級圖表系列中。我需要將x軸上的垂直線和y軸上的水平帶顯示為不同的顏色。
需要根據圖表中顯示的值添加垂直線和水平條。
這是我的代碼:
$('#container').highcharts({
title: {
text: 'Graph',
x: -20 //center
},
subtitle: {
text: '',
x: -20
},
credits: {
enabled: false
},
colors: ['red'],
xAxis: {
// categories: [],
title: {
text: 'Time'
},
},
yAxis: {
title: {
text: 'Rate'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
valueSuffix: ''
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle',
borderWidth: 0
},
series: [{
name: 'Heart Rate',
data: data_arr
}]
});
為此,您可以使用chart.xAxis[0].categories.length
訪問xAxis的長度,並使用chart.xAxis[0].categories[]
訪問xAxis元素的值。 檢查以下示例 :
$(function() {
$('#container').highcharts({
xAxis: {
categories: [10, 20, 30, 40, 50, 60, 70]
},
series: [{
data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6]
}]
});
// the button action
var hasPlotLine = false,
$button = $('#button'),
chart = $('#container').highcharts();
$button.click(function() {
for (i = 1; i < chart.xAxis[0].categories.length; i++) {
if (chart.xAxis[0].categories[i] > 30) {
chart.xAxis[0].addPlotLine({
value: i,
color: 'red',
width: 2,
id: 'plot-line-1'
});
}
}
});
});
要設置垂直/水平線/帶,請使用plotBands或/和plotLines選項:
對於行:
plotLines: [{
color: '#FF0000',
width: 2,
value: 5.5
}]
對於樂隊
plotBands: [{ // mark the weekend
color: '#FCFFC5',
from: Date.UTC(2010, 0, 2),
to: Date.UTC(2010, 0, 4)
}],
