我想用一些來自REST風格的web服務的數據填充折線圖(CanvasJS)。CanvasJS圖未填充
JSON數組來我看起來像:
[
[
{
"periodo": "2014-03-03",
"quantidade": 2
},
{
"periodo": "2014-09-13",
"quantidade": 1
},
{
"periodo": "2015-06-23",
"quantidade": 6
},
{
"periodo": "2015-06-24",
"quantidade": 2
},
{
"periodo": "2015-06-25",
"quantidade": 1
}
],
[
{
"periodo": "2015-06-23",
"quantidade": 1
}
]
]
即兩個陣列(我想在兩行變換圖)。在我的jQuery代碼,我加入了一些禮節這個JSON數組,像這樣:
var chartdata = [];
jQuery.each(data, function(i, val) {
var chart = {};
chart["type"] = "spline";
chart["showInLegend"] = true;
chart["dataPoints"] = val;
chartdata.push(chart);
});
最後我打電話抽屜:
var chart = new CanvasJS.Chart("chartContainer",{
animationEnabled: true,
zoomEnabled: true,
data: chartdata,
legend: {
cursor: "pointer",
itemclick: function (e) {
if (typeof(e.dataSeries.visible) === "undefined" || e.dataSeries.visible) {
e.dataSeries.visible = false;
} else {
e.dataSeries.visible = true;
}
chart.render();
}
}
});
但圖不被繪製。也沒有錯誤。我比較了我的最終JSON數組,它與CanvasJS example
相差無幾?
