【问题描述】:
我在我的应用程序中使用 Chart.js(版本:2.7.2),结果行中的一些标签相当长
var barCanvas = document.getElementById("canvasVoteNames");
var ctx = barCanvas.getContext('2d');
var numberWithCommas = function(x) {
return x.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");
};
var self = this;
var myChart = new Chart(ctx, { // stacked bar report https://jsfiddle.net/sdfx/hwx9awgn/
type: 'bar',
data: {
labels:monthsXCoordItems,
datasets: [
{
label: 'Correct Votes',
data: voteValuesCorrect,
borderWidth: 1, // The stroke width of the bar in pixels.
backgroundColor : formatColor('#05b932'), //rgba(0, 0, 0, 0.1), // The fill color of the bar. See Colors
borderColor: formatColor('#05b932'),// rgba(255, 0, 0, 0.1) // The color of the bar border.
hoverBackgroundColor : formatColor('#05b932'), // The fill colour of the bars when hovered.
hoverBorderColor: formatColor('#05b932'), // The stroke colour of the bars when hovered.
hoverBorderWidth : 1 // The stroke width of the bars when hovered.
},
{
label: 'Incorrect Votes',
data: voteValuesNoneCorrect,
borderWidth: 1, // The stroke width of the bar in pixels.
backgroundColor : formatColor('#b1a19a'), //rgba(0, 0, 0, 0.1), // The fill color of the bar. See Colors
borderColor: formatColor('#b1a19a'),// rgba(255, 0, 0, 0.1) // The color of the bar border.
hoverBackgroundColor : formatColor('#b1a19a'), // The fill colour of the bars when hovered.
hoverBorderColor: formatColor('#b1a19a'), // The stroke colour of the bars when hovered.
hoverBorderWidth : 1 // The stroke width of the bars when hovered.
},
]
},
options: { // options of Report By Vote Names
animation: {
duration: 10,
},
tooltips: { // tooltip text of Report By Vote Days ( 'bar' report )
mode: 'label',
callbacks: {
label: function(tooltipItem, data) {
return data.datasets[tooltipItem.datasetIndex].label + ": " + numberWithCommas(tooltipItem.yLabel);
}
}
}, // tooltips: { // tooltip text of Report By Vote Days ( 'bar' report )
scales: { // options for x and y scales
xAxes: [{
stacked: true, // Stacked bar charts can be used to show how one data series i
gridLines: { display: false },
}],
yAxes: [{
stacked: true, // Stacked bar charts can be used to show how one data series i
ticks: {
callback: function(value) { // on Y scale show only integer without decimals
if (Math.floor(value) === value) {
return value;
}
}, // callback: function(value) { return numberWithCommas(value); },
},
}],
}, // scales: { // options for x and y scales
legend: {display: true}
} // options: { // options of Report By Vote Names
}); // var myChart = new Chart(ctx, { // stacked bar report https://jsfiddle.net/sdfx/hwx9awgn/
}
我得到的图表就是我需要的 https://imgur.com/a/n1SsW7w 但是对于任何酒吧都有长标签,它看起来并不好,我没有找到是否有办法以某种方式修复它? 为什么标签的边距很大,而不是相对条?
xAxes 或附加图例的一些选项?
谢谢!
【问题讨论】:
-
对不起,我还在寻找一些决定。我在谷歌上搜索并找到了几个示例,但它们都带有短标签,并且没有类似我的问题......没有想法?
-
我找到了一个类似的例子并修改了一些标签以重复我的问题:jsfiddle.net/hwx9awgn/1259 xAxes 上的一些标签根本没有显示:实际上 1,3,5... 显示的标签可以是任何决定?
