我正在創建圖表，如下所示：
所以我可以單獨顯示圖表，但我不能在同一條圖表線上顯示兩個圖表。
<!DOCTYPE html>

<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.5.0/Chart.min.js"></script>
<body>
<canvas id="statisticChart" style="width:100%;max-width:600px"></canvas>
<script>
var xValues = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"];
var yValues = [7, 8, 8, 9, 9, 9, 10, 11, 14, 14, 15, 12];
new Chart("statisticChart", {
type: "line",
data: {
labels: xValues,
datasets: [{
fill: false,
lineTension: 0,
backgroundColor: "rgba(25,162,242,1)",
borderColor: "rgba(2, 92, 145, 1)",
data: yValues
}]
},
options: {
legend: { display: false },
scales: {
yAxes: [{ ticks: { min: 6, max: 16 } }],
}
}
});
var barColors = ["#19A2F2"];
Chart("statisticChart", {
type: "bar",
data: {
labels: xValues,
datasets: [{
backgroundColor: barColors,
data: yValues
}]
},
options: {
legend: { display: false },
title: {
display: true,
text: "World Wine Production 2018"
}
}
});
</script>
</body>
</html>
那你能看看嗎？此外我也關心css，所以我想用顏色#19A2F2顯示第二張圖表，在此先感謝。
uj5u.com熱心網友回復：
Chart.js 支持混合圖表——當然這僅涉及使用一個 Chart 實體。您需要做的就是獲取兩個單獨圖表的物件并將它們放入分配給 Charts屬性datasets的陣列中。data.datasets
例如：
var xValues = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"];
var yValues = [7, 8, 8, 9, 9, 9, 10, 11, 14, 14, 15, 12];
new Chart("statisticChart", {
type: "bar",
data: {
labels: xValues,
datasets: [{
type: "line",
fill: false,
lineTension: 0,
backgroundColor: "rgba(25,162,242,1)",
borderColor: "rgba(2, 92, 145, 1)",
data: yValues,
fill: false
},
{
type: "bar",
backgroundColor: "#19A2F2",
data: yValues
}
]
},
options: {
legend: {
display: false
},
scales: {
yAxes: [{
ticks: {
min: 6,
max: 16
}
}],
},
title: {
display: true,
text: "World Wine Production 2018"
}
}
});<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.5.0/Chart.min.js"></script>
