在下面的代码中我需要工具提示如下概率:40受众:5000 即在工具提示中我需要带有xAxes值的xAxes labelstring和带yAxes值的yAxes labelstring。如何实现这一点请帮助
var ctx = document.getElementById("myChart");
var myChart = new Chart(ctx, {
type: 'line',
data: {
datasets: [{
label: 'Audience',
data: [{x:12,y:9000}, {x:30, y:6000}, {x:40, y:5000},{x:52,y:4000},{x:70,y:3000},{x:92,y:2000}],
backgroundColor: 'rgba(255, 99, 132, 0.2)',
borderColor: 'rgba(255, 159, 64, 1)',
borderWidth: 1
}]
},
options: {
tooltips:
{
callbacks:
{
label: function(tooltipItem, data) {return data.datasets[tooltipItem.datasetIndex].label+':'+ tooltipItem.yLabel;
}
}
},
scales: {
xAxes: [{
type: 'linear',position: 'bottom',
scaleLabel:{labelString:"Probability",display:true},
ticks: {
beginAtZero:true,
max:100
}
}],
yAxes: [{
scaleLabel:{labelString:"Audience",display:true},
ticks: {
min: 1000
}
}]
}
}
});
答案 0 :(得分:0)
只需替换你的"回调"阻止这一个:
callbacks:
{
title: function() {
return '';
},
beforeLabel: function(tooltipItem, data) {
return 'Probability: ' + tooltipItem.xLabel + '%';
},
label: function(tooltipItem, data) {
return data.datasets[tooltipItem.datasetIndex].label+': '+ tooltipItem.yLabel;
}
}
