我的chart.js
var ctx_1 = document.getElementById('https_http').getContext('2d');
var myChart_1 = new Chart(ctx_1, {
type: 'horizontalBar',
data: {
labels: ['HTTPS Pages','HTTP Pages'],
datasets: [{
data: [ {{ $array_https_http[0] }}, {{ $array_https_http[1] }}],
backgroundColor: [
'rgb(81, 170, 120)',
'rgb(198, 222, 208)'
]
}]
},
options: {
showAllTooltips: true,
tooltips: {
enabled: true,
displayColors: false,
yPadding: 20,
xPadding: 30,
caretSize: 10,
backgroundColor: 'rgba(240, 240, 240, 1)',
bodyFontSize: 16,
bodyFontColor: 'rgb(50, 50, 50)',
borderColor: 'rgba(0,0,0,1)',
borderWidth: 1,
cornerRadius: 0,
yAlign: 'bottom',
xAlign: 'center',
position: 'custom',
custom: function(tooltip) {
if (!tooltip) return;
// disable displaying the color box;
tooltip.displayColors = false;
},
callbacks: {
// use label callback to return the desired label
label: function(tooltipItem, data) {
return tooltipItem.yLabel + " : " + tooltipItem.xLabel ;
},
// remove title
title: function(tooltipItem, data) {
return;
}
}
},
responsive: false,
legend: { display: false },
scales: {
yAxes: [{
ticks: {
beginAtZero:true,
},
gridLines: {
display: false
},
}],
xAxes: [{
ticks: {
stepSize:100
}
}],
}
}
});
我的工具提示代码
Chart.Tooltip.positioners.custom = function(elements, position) {
if (!elements.length)
return false;
var em = elements[0]._model;
return {
x: em.x-((em.x-em.base)/2),
y: em.y+em.height/4
}
}
有没有人可以帮助我如何像第二张图片一样将这些值放在小节之后。我只想显示该值以知道它的零。我的自定义工具提示是显示不同的悬停而不是默认值。感谢您的所有帮助,并在此先感谢您。

您可以使用chartjs.datalabel插件来满足需要。我为您创建了一个小提琴-> http://jsfiddle.net/Labkrpf4/
