如何在 CanvasJS 中从 4 个数组加载数据点以创建图表
How to load datapoints from 4 array in CanvasJS to create a chart
问:
我想使用图表 canvasjs 来显示 4 种不同的数据。 我的数据是过去 10 天内 4 个不同账户的余额,我想要天数的 x 轴和余额金额的 y 轴。
我的代码 :
const ColorBac = ["rgba(255, 0, 50, 0.2)", "rgba(27, 68, 128, 0.2)", "rgba(246, 162, 30, 0.2)", "rgba(23, 135, 95, 0.2)"];
const Colorborder = ["rgba(255, 0, 50, 0.6)", "rgba(27, 68, 128, 0.6)", "rgba(246, 162, 30, 0.6)", "rgba(23, 135, 95, 0.6)"];
Api = api('Chart');
console.log("load Api Array");
console.log(Api.ExData);
function setColor(chart) {
for (var i = 0; i < chart.options.data.length; i++) {
dataSeries = chart.options.data[i];
for (var j = 0; j < dataSeries.dataPoints.length; j++) {
if (dataSeries.dataPoints[j].y <= 0)
dataSeries.dataPoints[j].color = ColorBac[j];
}
}
}
function ShowChart() {
var dataPoints = [];
//GetData();
$.each(Api.ExData, function(index, Info) {
dataPoints.push({
x: parseInt(Info.fldHesabID),
y: parseInt(Info.fldMojoodi),
label: Info.fldDate,
mouseover: onMouseover,
});
});
console.log('load dataPoints');
console.log(dataPoints);
///////
var chart = new CanvasJS.Chart("chartContainer", {
animationEnabled: true,
theme: "light2", // "light1", "light2", "dark1", "dark2"
axisY: {
//title: "Reserves(MMbbl)"
//labelAngle: 30
},
axisX: {
interval: 1,
//minimum: 0,
// maximum: 20,
labelAngle: 30
},
data: [{
type: "line",
toolTipContent: "{label}: {y} ",
dataPoints: dataPoints,
}]
});
console.log('load Chart');
setColor(chart);
chart.render();
function onMouseover(e) {
createGauge(e.dataPoint.progressVal);
}
}
ShowChart();
console.log('end Chart');
<div id="chartContainer" style="height: 370px; width: 100%;border: 1px solid green;"></div>
