我的MVC Web应用程序中有一个简单的图表。现在我有一些过滤器会更新其click
事件的图表。实际上,click事件将使用ajax调用来更新图表。
这是我的图表:
$('#performance-cart').highcharts({
chart: {
type: 'area', backgroundColor: '#f5f7f7', style: { fontFamily: 'Roboto, Sans-serif', color: '#aeafb1' },
animation: {
duration: 1500,
easing: 'easeOutBounce'
}
},
xAxis: {
type: 'datetime',
labels: { style: { color: '#aeafb1' } }
},
yAxis: {
min: 0, max: 50, tickInterval: 10, gridLineColor: '#ebeded', gridLineWidth: 1,
title: { text: '' }, lineWidth: 0, labels: { align: 'right', style: { color: '#aeafb1' } }
},
title: { text: '' },
tooltip: {
useHTML: true, headerFormat: '<h3 style="color:#ffffff;font-weight:300;padding: 3px 12px;">{point.y:,.1f}</br>',
backgroundColor: '#515757', pointFormat: '{series.name}'
},
legend: {
itemStyle: { color: '#838589' }, symbolWidth: 12, symbolHeight: 5, itemWidth: 80, symbolRadius: 0,
itemMarginBottom: 10, backgroundColor: '#f5f7f7', verticalAlign: 'top', borderWidth: 0, x: -498, y: 10
},
plotOptions: {
area: {
fillOpacity: 0.2, cursor: 'pointer', marker: {
symbol: 'circle', fillColor: '#FFFFFF', lineWidth: 2, lineColor: null,
allowPointSelect: true
}
},
line: {
fillOpacity: 0.2, cursor: 'pointer', marker: {
symbol: 'circle', fillColor: '#FFFFFF', lineWidth: 2, lineColor: null,
allowPointSelect: true
}
},
column: {
fillOpacity: 0.2, cursor: 'pointer', marker: {
symbol: 'circle', fillColor: '#FFFFFF', lineWidth: 2, lineColor: null,
allowPointSelect: true
}
},
series: {
pointStart: myIssueResolvedStartDate,
pointInterval: 24 * 3600 * 1000 // one day
}
},
series: [{
name: 'Issues', color: '#ff3806',
data: myIssueData,
marker: { states: { hover: { fillColor: '#ff3806', lineColor: '#ffffff', lineWidth: 2 } } }
}, {
name: 'Resolved', color: '#1da9dd',
data: myResolvedData,
marker: { states: { hover: { fillColor: '#1da9dd', lineColor: '#ffffff', lineWidth: 2 } } }
}]
});
现在在我的ajax调用中,我做了类似的事情来更新图表:
var chart = $('#performance-cart').highcharts();
chart.options.plotOptions.series.pointStart = newDate; \\newDate = 1404086400000
chart.series[0].setData(issue, true);
chart.series[1].setData(resolve, true);
问题是,chart.options.plotOptions.series.pointStart = newDate;
没有更新pointStart。我检查了newDate
变量中的值,并以UTC格式显示了完美的日期。系列数据正在更新。
我相信我写的语法错误或者是针对pointStart的。如果有人能够指出问题,我真的很感激。

您无法实时更新plotOptions
(也许有一些黑客入侵,但我们不提供官方API方法)。但是,您可以更新每个系列,如下所示:
var chart = $('#performance-cart').highcharts();
chart.series[0].update({
data: issue,
pointStart: newDate
}, true);
chart.series[1].update({
data: resolve,
pointStart: newDate
}, true);
