如何在Google ColumnChart中放置图标 [英] How to place an icon inside Google ColumnChart
问题描述
我有一个只有一列的columnchart栏,我想在该栏的顶部放置一个图标,该栏是随机随机变化的。我检查了Internet和Google Chart API上的一些资源,但找不到解决方案。可以看到下面的代码属于我的图表
这里是演示,也可以让您了解我的网格和图表
我尝试了什么下方以生成下面的柱形图
TS文件
title ='Tempe批准;
type = ColumnChart;
data = [[’’,25]];
columnNames = ['元素','温度'];
options = {
backgroundColor:'#fafafa',
图例:{position:'none'},
动画:{
持续时间:250,
缓动:'ease-in-out',
启动:true,
},
条形:{
groupWidth:50
},
hAxis :{{
baselineColor:'none',
ticks:[]
},
vAxis:{
baselineColor:'none',
ticks:[ ],
viewWindow:{
max:40,
min:0
}
}
}
width = 100;
height = 300;
ngOnInit()
{
interval(2000).subscribe(()=> {
this.data = [
['',(Math.random ()* 41)],
];
});
}
HTML文件
< div style = border-style:solid; border-width:1px;>
< google-chart #chart
[title] = title
[type] = type
[data] = data
[columnNames ] = columnNames
[options] = options
[width] = width
[height] = height
>
< / google-chart>
< / div>
您可以使用图表方法<$ c $添加图标c> getChartLayoutInterface()& getBoundingBox()
在图表的就绪
事件,找到条形图的位置,
然后放置图像。
虽然不是成角度的,但它的工作原理相同,
请参见以下工作片段...
google.charts.load('current',{package:['corechart']})。then(function() {var data = new google.visualization.DataTable(); data.addColumn('string','X'); data.addColumn('number','Y'); data.addRows([[{v:'a ',p:{thumb:'clone_old.png'}},20],[{v:'b',p:{thumb:'boba_fett.png'}},15],[{v:'c', p:{thumb:'jango_fett.png'}},30],[{v:'d',p:{thumb:'clone_3.png'}},5],[{v:'e',p: {thumb:'clone_2.png'}},25]]); var options = {图注:'none'}; var container = document.getElementById('chart_div'); var containerBounds = container.getBoundingClientRect(); var chart = new google.visualization.ColumnChart(container); google.visualization.events。 addListener(chart,'ready',function(){var chartLayout = chart.getChartLayoutInterface(); for(var i = 0; i< data.getNumberOfRows(); i ++){var barBounds = chartLayout.getBoundingBox(’bar#0#’+ i); var path =‘http://findicons.com/files/icons/512/star_wars/32/’; var thumb = container.appendChild(document.createElement(’img’)); thumb.src =路径+ data.getProperty(i,0,'thumb'); thumb.style.position =绝对; thumb.style.top =(barBounds.top + containerBounds.top-40)+‘px’; thumb.style.left =(barBounds.left + containerBounds.left +(barBounds.width / 2)-16)+‘px’; }}); chart.draw(data,options);});

I have columnchart bar which has one column and I wanna place an icon top of the bar.This bar is dynamically changing as randomly.I checked some sources on the internet and Google Chart API but couldn't find a solution.Is there any way to do that?Below you can see the code belongs to my chart
Here it's demo to give you idea about my Grid and Chart also
https://stackblitz.com/edit/angular-pt2kha?file=app/grid-list-overview-example.html
Here what I expect to see
What I tried below to generate this Column Chart below
TS File
title= 'Temperature';
type = 'ColumnChart';
data= [['',25]];
columnNames= ['Element', 'Temperature'];
options= {
backgroundColor: '#fafafa',
legend: {position: 'none'},
animation: {
duration: 250,
easing: 'ease-in-out',
startup: true,
},
bar: {
groupWidth: 50
},
hAxis: {
baselineColor: 'none',
ticks: []
},
vAxis: {
baselineColor: 'none',
ticks: [],
viewWindow: {
max:40,
min:0
}
}
}
width=100;
height=300;
ngOnInit()
{
interval(2000).subscribe(()=>{
this.data = [
['', (Math.random() * 41)],
];
});
}
HTML File
<div style="border-style:solid;border-width:1px;">
<google-chart #chart
[title]="title"
[type]="type"
[data]="data"
[columnNames]="columnNames"
[options]="options"
[width]="width"
[height]="height"
>
</google-chart>
</div>
you can add icons using chart methods getChartLayoutInterface()
& getBoundingBox()
on the chart's 'ready'
event, find the position of the bar,
then place the image.
although not angular, it will work the same,
see following working snippet...
google.charts.load('current', {
packages: ['corechart']
}).then(function () {
var data = new google.visualization.DataTable();
data.addColumn('string', 'X');
data.addColumn('number', 'Y');
data.addRows([
[{v: 'a', p: {thumb: 'clone_old.png'}}, 20],
[{v: 'b', p: {thumb: 'boba_fett.png'}}, 15],
[{v: 'c', p: {thumb: 'jango_fett.png'}}, 30],
[{v: 'd', p: {thumb: 'clone_3.png'}}, 5],
[{v: 'e', p: {thumb: 'clone_2.png'}}, 25]
]);
var options = {
legend: 'none'
};
var container = document.getElementById('chart_div');
var containerBounds = container.getBoundingClientRect();
var chart = new google.visualization.ColumnChart(container);
google.visualization.events.addListener(chart, 'ready', function () {
var chartLayout = chart.getChartLayoutInterface();
for (var i = 0; i < data.getNumberOfRows(); i++) {
var barBounds = chartLayout.getBoundingBox('bar#0#' + i);
var path = 'http://findicons.com/files/icons/512/star_wars/32/';
var thumb = container.appendChild(document.createElement('img'));
thumb.src = path + data.getProperty(i, 0, 'thumb');
thumb.style.position = 'absolute';
thumb.style.top = (barBounds.top + containerBounds.top - 40) + 'px';
thumb.style.left = (barBounds.left + containerBounds.left + (barBounds.width / 2) - 16) + 'px';
}
});
chart.draw(data, options);
});
