我正在尝试将按列分组的数据显示为多个系列。主要有三个要求:
到目前为止,似乎tickInterval非常依赖于提供的数据,而Highchart在某些情况下忽略它,例如下面的那个。有没有办法让它在我的场景中打勾?即使没有数据,是否可以添加刻度?
$('#container').highcharts({
global: {
useUTC: false
},
chart: {
zoomType: false,
type: 'column'
},
xAxis: {
type: 'datetime',
ordinal: false,
startOnTick: false,
endOnTick: false,
minPadding: 0,
maxPadding: 0,
tickInterval: 3600 * 1000,
minTickInterval: 3600 * 1000
},
plotOptions: {
column: {
stacking: 'normal',
column: {
pointPadding: 0,
borderWidth: 0,
grouping: true
}
}
},
series: [{"name":"One","data":[[1.424304e+12,1],[1.4243076e+12,2],[1.4243148e+12,1],[1.4243301e+12,1],[1.4243364e+12,1],[1.4243436e+12,1],[1.4243472e+12,1],[1.4243526e+12,1],[1.4243535e+12,1],[1.4243544e+12,1],[1.4243625e+12,1],[1.4243652e+12,2],[1.424367e+12,1],[1.4243688e+12,8],[1.4243724e+12,3],[1.4243733e+12,1],[1.424376e+12,8],[1.4243814e+12,3],[1.4243841e+12,1]]},{"name":"Two","data":[[1.424304e+12,1],[1.4243112e+12,1],[1.4243292e+12,1],[1.4243436e+12,1],[1.4243616e+12,1],[1.4243652e+12,3],[1.4243724e+12,1],[1.4243868e+12,1]]},{"name":"Seven","data":[[1.4243706e+12,1],[1.4243814e+12,1]]}]
});

点之间有不规则的间隔,因此Highcharts无法真正计算点之间的适当距离。这导致xAxis上的间隔问题 - 解决方法是将pointRange
设置为例如1/10小时:jsfiddle.net/qn6romsf/7 - 如果你不能设置pointRange
,那么尝试使用tickPositioner

也许我的样本会帮助你。逻辑是下一步:1)发送ajax每分钟检索数据(60个元素)2)从该列表推送一个元素到系列3)所以图表每秒更新。
function getLoadApp(){
var d;
var ar=[];
for(var i=0; i<60; i++){
ar[i] = 0;
}
$.ajax({
type: "POST",
url: "./dashboard",
async: false,
data: {
ajax: true,
oper: "loadapp"
},
success: function(data) {
d = jQuery.parseJSON(data);
for(var i=0; i<d.length; i++){
ar[Number(d[i].SEC)] = Number(d[i].COUNT);
}
loadappOneMin = loadappOneMin.concat(ar);
}
});
}
getLoadApp();
$('#loadapp').highcharts({
lang: {
noData : "На данный момент данные отсутствуют"
},
chart: {
type: 'spline',
animation: Highcharts.svg, // don't animate in old IE
marginRight: 10,
borderWidth: 1,
borderRadius: 4,
borderColor: '#E8E8E8',
events: {
load: function() {
// set up the updating of the chart each second
var series = this.series[0];
//каждую сек выталкиваем 1ый из списка
setInterval(function() {
loadappOneSec = loadappOneMin.shift();
if(! loadappOneSec){
loadappOneSec = 0;
};
d = new Date();
var x = d.getTime();
series.addPoint([x, loadappOneSec], true, true);
}, timeInterval);
//каждую мин обн.-ем список
setInterval('getLoadApp()', 60*timeInterval);
}
}
