我想把 Yaxis 从实数变成整数,这是图片,请帮我解决这个问题
这是我的代码
var lineChartData = {
labels: time,
datasets: [{
label: "Số người đăng kí ủng hộ",
borderColor: window.chartColors.red,
pointBackgroundColor: window.chartColors.red,
fill: false,
data: people_isProcessing
}, {
label: "Số người đã ủng hộ",
borderColor: window.chartColors.purple,
pointBackgroundColor: window.chartColors.purple,
fill: false,
data: people_isReceived
}]
};
这是我的图表选项
window.onload = function() {
var chartEl = document.getElementById("chart");
window.myLine = new Chart(chartEl, {
type: 'line',
data: lineChartData,
options: {
title: {
display: true,
text: 'Kindmate - Chart Static Donate'
},
tooltips: {
enabled: true,
mode: 'index',
position: 'nearest',
custom: customTooltips
}
}
});
});
最佳答案
在您的情况下,您可以将 y 轴刻度的 stepSize
属性设置为 1
,以更改从 float 到整数的 y 轴值。
options: {
scales: {
yAxes: [{
ticks: {
stepSize: 1
}
}]
},
...
}

var chart = new Chart(ctx, {
type: 'line',
data: {
labels: ['Jan', 'Feb', 'Mar', 'Apr'],
datasets: [{
label: '# of votes',
data: [1, 2, 3, 4]
}]
},
options: {
scales: {
yAxes: [{
ticks: {
stepSize: 1
}
}]
}
}
});
