Highcharts - 保持点击显示工具提示 [英] Highcharts - Keep tooltip showing on click
问题描述
我有一张高图,我允许用户动态创建自己的标志。现在我想能够点击国旗本身,并能够保持它的工具提示显示整个时间,直到我再次点击国旗。原因是为了让用户给点赋予特殊的含义,当他们将图形保存为图像时,我希望它显示留下的工具提示信息。
任何人都知道如何做到这一点或去做这件事?我无法弄清楚如何访问标志工具提示
plotOptions:{
系列:{
allowPointSelect:true,
动画:false,
dataGrouping:{
force:true,
平滑:true
}
},
line :{
allowPointSelect:true,
animation:false,
point:{
events:{
click:function(){
var thePoint = this ;
var previousFlag = findFlag(thePoint);
if(previousFlag!= null){
previousFlag.remove();
} else {
createFlagForm(thePoint);
}
}
}
}
},
标记:{
point:{
events:{
点击:function(){
//如何访问工具提示?这意味着标记点本身
}
}
},
tooltip:{
useHTML:true,
xDateFormat:%B-%e- %Y%H:%M
}
}
},
我只是鞭打了这件事。当你点击一个点时,它会持续工具提示。它通过克隆tooltip svg元素并将其附加到图上来实现。
这是一个 fiddle 。
$(function(){
cloneToolTip = null;
chart = new Highcharts.Chart({
图:{
renderTo:'container'
},
xAxis:{
categories: ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec']
$,
plotOptions:{
series:{
cursor:'pointer',
point:{
events:{
单击:function(){
if(cloneToolTip)
{
chart.container.firstChild.removeChild(cloneToolTip);
}
cloneToolTip = this.series.chart.tooltip.label.element.cloneNode(true);
chart.container.firstChild.appendChild(cloneToolTip);
}
}
}
}
},

}]
});
});
I have a highcharts graph, and I allowed the user to dynamically create their own Flags. Now I want to be able to click on the flag itself and be able to keep it's tooltip showing the whole time until I click on the flag again. The reason for this is to allow the user to give special meaning to points, and when they save the graph as an image, I want it to show the tooltip information they left on.
Anyone know how to do this or go about this? I can't figure out how to access the flags tooltip
plotOptions: {
series: {
allowPointSelect: true,
animation: false,
dataGrouping: {
force: true,
smoothed: true
}
},
line: {
allowPointSelect: true,
animation: false,
point: {
events: {
click: function () {
var thePoint = this;
var previousFlag = findFlag(thePoint);
if (previousFlag != null) {
previousFlag.remove();
} else {
createFlagForm(thePoint);
}
}
}
}
},
flags: {
point: {
events: {
click: function() {
//How to access the tooltip? this means the flag point itself
}
}
},
tooltip: {
useHTML: true,
xDateFormat: "%B-%e-%Y %H:%M"
}
}
},
I just whipped this up. When you click a point it will persist the tooltip. It does this by cloning the tooltip svg element and appending it to the plot.
Here's a fiddle.
$(function () {
cloneToolTip = null;
chart = new Highcharts.Chart({
chart: {
renderTo: 'container'
},
xAxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
},
plotOptions: {
series: {
cursor: 'pointer',
point: {
events: {
click: function() {
if (cloneToolTip)
{
chart.container.firstChild.removeChild(cloneToolTip);
}
cloneToolTip = this.series.chart.tooltip.label.element.cloneNode(true);
chart.container.firstChild.appendChild(cloneToolTip);
}
}
}
}
},
series: [{
data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
}]
});
});
