Can Chart.js v2.x能夠使用一個y軸生成包含2個拆散線的組合堆積條形圖嗎?如果是這樣,怎麼樣?Chart.js v2 - 組合堆積條形圖和2個拆散線
小提琴有2個y軸。下降線,如果右側y軸的最大值爲6000,那麼渲染效果會更好,左軸也是如此。
以下是供參考的代碼。
// set default no fill beneath the line
Chart.defaults.global.elements.line.fill = false;
// stacked bar with 2 unstacked lines - nope
var barChartData = {
labels: ['2016', '2017', '2018', '2019'],
datasets: [{
type: 'bar',
label: 'a',
yAxisID: "y-axis-0",
backgroundColor: "rgba(217,83,79,0.75)",
data: [1000, 2000, 4000, 5000]
}, {
type: 'bar',
label: 'b',
yAxisID: "y-axis-0",
backgroundColor: "rgba(92,184,92,0.75)",
data: [500, 600, 700, 800]
}, {
type: 'line',
label: 'c',
yAxisID: "y-axis-0",
backgroundColor: "rgba(51,51,51,0.5)",
data: [1500, 2600, 4700, 5800]
}, {
type: 'line',
label: 'd',
yAxisID: "y-axis-1",
backgroundColor: "rgba(151,187,205,0.5)",
data: [5000, 3000, 1000, 0]
}]
};
var ctx = document.getElementById("chart").getContext("2d");
// allocate and initialize a chart
var ch = new Chart(ctx, {
type: 'bar',
data: barChartData,
options: {
title: {
display: true,
text: "Chart.js Bar Chart - Stacked"
},
tooltips: {
mode: 'label'
},
responsive: true,
scales: {
xAxes: [{
stacked: true
}],
yAxes: [{
stacked: true,
position: "left",
id: "y-axis-0",
}, {
stacked: false,
position: "right",
id: "y-axis-1",
}]
}
}
});
