我有一个帕累托图(使用 Chart.js 版本:2.0.2),我需要在条形图内和线下显示值。
任何帮助将不胜感激:
这是代码(希望它对某人有用):
<canvas id="canvas"></canvas>
<script type="text/javascript">
var data = {
labels: ["8","7","9","11","10"],
datasets: [{
type: "line",
label: "Acumulado",
borderColor: "#BA1E14",
backgroundColor: "#BA1E14",
pointBorderWidth: 5,
fill: false,
data: [34.04,57.45,76.60,89.36,100.00],
yAxisID: 'y-axis-2'
},{
type: "bar",
label: "Asistencia",
borderColor: "#56B513",
backgroundColor: "#56B513",
data: [16,11,9,6,5],
yAxisID: 'y-axis-1'
},{
type: "bar",
label: "Solución",
borderColor: "#000FAA",
backgroundColor: "#000FAA",
data: [16,11,9,6,5],
yAxisID: 'y-axis-1'
}]
};
var options = {
scales: {
xAxes: [{
stacked: true,
scaleLabel: {
display: true,
labelString: "Estaciones"
}
}],
yAxes: [{
type: "linear",
position: "left",
id: "y-axis-1",
stacked: true,
ticks: {
suggestedMin: 0
},
scaleLabel: {
display: true,
labelString: "Minutos"
}
},{
type: "linear",
position: "right",
id: "y-axis-2",
ticks: {
suggestedMin: 0,
callback: function(value) {
return value + "%";
}
},
scaleLabel: {
display: true,
labelString: "Porcentaje"
}
}]
}
};
window.onload = function() {
var ctx = document.getElementById("canvas").getContext("2d");
window.myBar = new Chart(ctx, {
type: 'bar',
data: data,
options: options
});
};
</script>
