我想在ChartJS上创建条形图,但是尝试消除Y轴0条和第一个条之间的“间隙”时,我没有成功。甚至有可能吗?
HTML
<canvas id="openedCanvas" height="230" width="680"></canvas>
JavaScript
var data = {
labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
datasets: [{
label: '# of Votes',
data: [12, 19, 3, 5, 2, 3],
backgroundColor: [
'rgba(255, 99, 132, 0.2)',
'rgba(54, 162, 235, 0.2)',
'rgba(255, 206, 86, 0.2)',
'rgba(75, 192, 192, 0.2)',
'rgba(153, 102, 255, 0.2)',
'rgba(255, 159, 64, 0.2)'
],
borderColor: [
'rgba(255,99,132,1)',
'rgba(54, 162, 235, 1)',
'rgba(255, 206, 86, 1)',
'rgba(75, 192, 192, 1)',
'rgba(153, 102, 255, 1)',
'rgba(255, 159, 64, 1)'
],
borderWidth: 1
}]
};
var options = {}
var chart = new Chart($('#openedCanvas'), {
type: 'bar',
data: data,
options: options
});
这是正在运行的Codepen https://codepen.io/fermijs/pen/ZmPRaB
谢谢:)

要获得预期结果,请对x轴使用scales选项
https://www.chartjs.org/docs/latest/charts/bar.html?h=scales的barPercentage与categoryPercentage部分
1.0都将堆叠在一起,因此请根据您的要求进行调整
scales: {
xAxes: [{
categoryPercentage: 0.99,
barPercentage: 1.0
}]
}
