我有一个使用Chart.js的带有标签的数据集。我想将标签分成两行,并使用换行符。
我尝试过PackageManager p = getPackageManager();
ComponentName componentName = new ComponentName(this, com.apps.MainActivity.class);
p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);
和ActivityNotFoundException
,但都没有用。
<br />
第一个标签应显示为...
(A)
醒来
但它最终看起来像...
(A)
\n
醒来(A)醒来
答案 0 :(得分:3)
看这张示例图https://www.chartjs.org/samples/latest/scales/multiline-labels.html,我发现多行标签是可行的。
我查看了上面示例的源代码,对于多行标签,它们在数组中具有每条多行,而数组中的每个元素都在其自己的行中呈现。
例如:
labels: [['(A)', 'Waking'], '(B)', '(C)', '(D)'],
请参见下面的演示:
var randomScalingFactor = function() {
return Math.round(Math.random() * 100);
};
window.chartColors = {
red: 'rgb(255, 99, 132)',
orange: 'rgb(255, 159, 64)',
yellow: 'rgb(255, 205, 86)',
green: 'rgb(75, 192, 192)',
blue: 'rgb(54, 162, 235)',
purple: 'rgb(153, 102, 255)',
grey: 'rgb(201, 203, 207)'
};
var config = {
type: 'line',
data: {
labels: [
['(A)', 'Walking'], '(B)', '(C)', '(D)'],
datasets: [{
label: 'My First dataset',
fill: false,
backgroundColor: window.chartColors.red,
borderColor: window.chartColors.red,
data: [
randomScalingFactor(),
randomScalingFactor(),
randomScalingFactor(),
randomScalingFactor()
]
}, {
label: 'My Second dataset',
fill: false,
backgroundColor: window.chartColors.blue,
borderColor: window.chartColors.blue,
data: [
randomScalingFactor(),
randomScalingFactor(),
randomScalingFactor(),
randomScalingFactor()
],
}]
},
options: {
responsive: true,
title: {
display: true,
text: 'Chart with Multiline Labels'
},
}
};
window.onload = function() {
var ctx = document.getElementById('canvas').getContext('2d');
window.myLine = new Chart(ctx, config);
};
