Highcharts:通过点击显示多个工具提示,反之亦然 [英] Highcharts: display multiple tooltips by click and vice versa
问题描述
- 点击点 - > tooltip被永久克隆并显示
- 如果您再次点击相同的点,克隆将被删除
- 允许同时显示多个工具提示
我工作的大部分东西都存在,但有一些小问题需要解决:
$(function(){
cloneToolTip = null;
checkx = [];
checky = [];
clone = [];
del = [];
chart = new Highcharts.Chart({
图:{
renderTo:'container'
} ,
xAxis:{
categories:['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep' ,'Oct','Nov','Dec']
},
plotOptions:{
系列:{
cursor:'pointer',
point:{
events:{
click:function(){
//检查点是否已被点击
if(checkx.indexOf(event.point.x)> = 1& checky.indexOf(event.point.y)> = 1){
//移除工具提示
chart.container.firstChild.removeChild(clone [checkx.indexOf(event.point.x)]) ;
//移除xy坐标并从数组中克隆 - > tooltip可以再次显示
/*del=checkx.indexOf (event.point.x);
clone.splice(del,1);
checky.splice(del,1);
checkx.splice(del,1); * /
}
// cloneToolTip = null;
if(checkx.indexOf(event.point.x)== -1& checky.indexOf(event.point.y)== -1){
cloneToolTip = this.series.chart。 tooltip.label.element.cloneNode(真);
chart.container.firstChild.appendChild(cloneToolTip);
//保存坐标和工具提示对象
checkx.push(event.point.x);
checky.push(event.point.y);
clone.push(cloneToolTip);
}
}
}
}
}
},
系列:[{
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]
}]
});
});
我的问题是:
- 第一个选定的工具提示,也就是它的克隆,不能被移除
- 删除后,不能再次显示工具提示。我尝试删除所有三个数组中的相应条目(注释代码块),但是在更正后没有任何克隆被删除 我真的是一个初学者和谷歌很多找到例子,但这个问题我不能自己修复。有人可以给我一个提示吗?
- click on the point --> tooltip is cloned and displayed permanently
- if you click on the same point again, the clone is removed
- multiple tooltips are allowed to be displayed at the same time
谢谢!
问题是从 inArray()
返回的值。它将返回数组的索引,所以它从 0
开始,而你的 if
语句与 1
。
另外,我做了一些其他更改(否则在Chrome中会出现一些错误)。例如: http://jsfiddle.net/7vkZV/
I search for a way to display a tooltip permanently:
Most of the things I got to work but there are some little issues that needs to be fixed:
$(function () {
cloneToolTip = null;
checkx = [];
checky = [];
clone = [];
del = [];
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 () {
//check if point was already clicked
if (checkx.indexOf(event.point.x) >= 1 & checky.indexOf(event.point.y) >= 1) {
//remove tooltip
chart.container.firstChild.removeChild(clone[checkx.indexOf(event.point.x)]);
//remove xy coordinate and clone from array --> tooltip can be displayed again
/*del=checkx.indexOf(event.point.x);
clone.splice(del, 1);
checky.splice(del, 1);
checkx.splice(del, 1);*/
}
//cloneToolTip=null;
if (checkx.indexOf(event.point.x) == -1 & checky.indexOf(event.point.y) == -1) {
cloneToolTip = this.series.chart.tooltip.label.element.cloneNode(true);
chart.container.firstChild.appendChild(cloneToolTip);
//save coordinates and tooltip object
checkx.push(event.point.x);
checky.push(event.point.y);
clone.push(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]
}]
});
});
My problems are:
- the first selected tooltip, i.e. its clone, cannot be removed
- When a clone is removed, you cannot display the tooltip again permanently. I tried to remove the corresponding entries in all three arrays (commented code block) but then none of the clones is removed after this correction
I'm really a beginner and google a lot to find examples but this problem I could not fix on my own. Can someone give me a hint?
Thanks!
The problem is with value returned from inArray()
. It will return index of array, so it start from 0
, while your if
statement comapres with 1
.
Also, I have made some other changes (otherwise in Chrome I get some errors). Example: http://jsfiddle.net/7vkZV/
