我創建這樣變化ChartJs軸標題動態
if (userLanguageCode === "es") {
customTooltipFormat = 'DD/MM/YYYY, HH:mm:ss';
customDisplayFormats = {
'millisecond': 'SSS [ms]',
'second': 'HH:mm:ss', // 11:20:01 AM
'minute': 'D/MM/YY HH:mm', // 11:20:01 AM
'hour': 'D/MM/YY HH[h]', // Sept 4, 5PM
'day': 'D/MM/YYYY', // Sep 4 2015
'week': 'll', // Week 46, or maybe "[W]WW - YYYY" ?
'month': 'MMM YYYY', // Sept 2015
'quarter': '[Q]Q - YYYY', // Q3
'year': 'YYYY', // 2015
};
}
Chart.defaults.global.responsive = true;
Chart.defaults.global.animation = false;
datosChartHistoricos = {
labels: [],
datasets: [{
label: textoValor,
backgroundColor: "rgba(0,181,255,0.5)",
fill: chartWithIncrementValues? true: false,
borderColor: "rgba(0,192,192,1)",
pointBorderColor: "rgba(0,181,255,1)",
pointBackgroundColor: "rgba(255,255,255,1)",
pointBorderWidth: 1,
data: []
}]
};
var ctx = document.getElementById("grafica").getContext("2d");
chartHistoricos = new Chart(ctx, {
type: chartWithIncrementValues? "bar" : "line",
data: datosChartHistoricos,
options: {
responsive: true,
elements: {
rectangle: {
borderWidth: 1,
borderColor: 'rgb(0, 0, 0)',
borderSkipped: 'bottom'
}
},
scales: {
xAxes: [{
type: "time",
time: {
tooltipFormat: customTooltipFormat,
displayFormats: customDisplayFormats,
}
}, ],
yAxes: [{
scaleLabel: {
display: true,
labelString: textoValor + " (" + unidadesValor + ")"
}
}]
},
legend: {
display: false,
}
}
});
這是圖表,默認的配置中,數據被動態地添加一個圖表,但用戶可以選擇不同的數據值來顯示,如溫度,distance ...爲了做到這一點,我只是改變了數據集和標籤的數據值,但我不知道如何改變yAxis標籤,當我改變數據集的值。初始化標題是可以的。
任何提示?
謝謝!
使用螢火蟲調試網頁。使用console.log(chartHistoricos)我可以看到所有可以訪問的對象,但軸對象內沒有「labelString」... –
