我正在使用带有向下钻取功能的图表,并且我允许选择一个点(=单击)。在事件单击时,我借助 AJAX 创建一个 HTML 表来列出与计数相关的实体(如果我看到 5 个项目,通过单击它我将看到这 5 个项目是谁并列出它们)。这成为深入的第二/第三级别(取决于我单击了图表中第二级别的第一级别)
但是,我想删除向上钻取事件中第一级的选择。
这是我的代码(已编辑):
编辑 我正在添加这样的系列(sample found here):
$(function() {
var myChart = new Highcharts.Chart({
chart: {
type: 'column',
renderTo: 'drillDownContainer',
// Deactivate drilldown by selection.
// See reason below in the drilldown method.
selection: function(event) {
return false;
},
drilldown: function(e) {
// Deactivate click on serie. To drilldown, the user should click on the category
if (e.category === undefined)
{
return;
}
// Set subTitle (2nd param) by point name without modify Title
// Giving 1st param as null tells the text will be for the subTitle,.
// For Title, remove the null 1st param and let text.
this.setTitle(null, { text: e.point.name });
if (!e.seriesOptions) {
var chart = this,
drilldowns = {
'Social': [
{"name":"Serie 1","data": [{"id":113,"name":"my data","y":14}
]}
]
};
var categorySeries = drilldowns[e.point.name];
var series;
for (var i = 0; i < categorySeries.length; i++) {
if (categorySeries[i].name === e.point.series.name) {
series = categorySeries[i];
break;
}
}
chart.addSingleSeriesAsDrilldown(e.point, series);
drilldownsAdded++;
// Buffers the number of drilldown added and once the number of series has been reached, the drill down is applied
// So, can't navigate by clicking to a single item.
// However, simply click on the category (xAxis) and then unselect the other series by clicking on legend
// The click has been disabled.
if (drilldownsAdded === 3) {
drilldownsAdded = 0;
chart.applyDrilldown();
}
}
},
drillup: function(e) {
this.setTitle(null, { text: '' }); // Erase subTitle when back to original view
$('#ajaxContainer').html(''); // Remove the table drilldown level3
},
drillupall: function(e) {
debugger;
console.log(this.series);
console.log(this.series.length);
for(i = 0; i < this.series.length; i++)
{
console.log("i = " + i);
console.log(this.series[i].data.length);
for (d = 0; i < this.series[i].data.length; d++)
{
console.log("d = " + d);
console.log(this.series[i].data[d].selected);
}
}
}
}
}); -- End of myChartdeclaration
myChart.addSeries({
color: colorsArray['impact101'],
name: '1-Modéré',
data: [
{
id: '101',
name: 'Type 1',
y: 64,
drilldown: true
},
{
id: '102',
name: 'Type 2',
y: 41,
drilldown: true
}]
}, true);
});

我想做什么? (编辑) 如果我在第二级选择一个点,然后返回到第一级,然后返回到相同的向下钻取数据,则不再选择之前选择的点。 然而,对于第一级,选择仍然存在。
在drillup
事件中,this.series[x].data[y]对应第2层的数据。很明显,因为所有系列的深入分析尚未完成,但事件引发的数量与系列一样多。
在 drillupall
事件中,我得到了正确的系列。我可以在调试中看到我的 3 系列,但它们都没有任何数据。因此,我无法按照下面评论中的建议应用 this.series[i].data[d].selected
。
我使用的是 Highcharts 5.0.9。
有什么想法可以帮助我吗?
感谢您的帮助。
最佳答案
我在 Highcharts 论坛上得到了帮助。 See here .
这是答案(以防上面的链接将来不起作用):
In this case you can change the state of a specific point with Point.select() function. Take a look at the example posted below. It works like that: in drillup() event there is a call of getSelectedPoints() which returns all selected points from the base series. Next, there is a call of select() function with false as an argument on a selected point to unselect it. In addition, the call of the getSelectedPoints() is located in a timeout, otherwise it would return an empty array (see https://github.com/highcharts/highcharts/issues/5583).
CODE:
setTimeout(function() { selectedPoints =
chart.getSelectedPoints()[0];
chart.getSelectedPoints()[0].select(false); }, 0);
API Reference: http://api.highcharts.com/highcharts/Ch ... ctedPoints http://api.highcharts.com/highcharts/Point.select
Examples: http://jsfiddle.net/d_paul/smshk0b2/
因此,现在是解决问题的代码:
drillupall: function(e) {
this.setTitle(null, { text: '' }); // Erase subTitle when back to original view
$('#ajaxContainer').html(''); // Remove the table drilldown level3
var chart = this,
selectedPoints;
setTimeout(function() {
selectedPoints = chart.getSelectedPoints()[0];
// Ensure there is any selectedPoints to unselect
if (selectedPoints != null)
{
selectedPoints.select(false);
}
}, 0);
