问题描述
无法将新数据绑定到D3 BubbleChart。我对API的AJAX调用得到了很好的JSON回复。我检查了答复,它获得的数据格式与用于初始设置图表的硬编码数据中定义的格式相同。我必须遗漏一些东西,因为我的图表没有显示新数据。我需要重绘图表吗?以下是我的尝试
我尝试过:
Having trouble binding new data to a D3 BubbleChart. My AJAX call to the API is getting a good JSON reply. I checked the reply and it is getting data in the same format as defined in the hardcoded data used to initially setup the chart. I must be missing something because my chart does not show the new data. Do I need to redraw the chart? Below is what I have tried
What I have tried:
$(document).ready(function () {
var uri = 'api/testing';
$.getJSON(uri, function (data, error) {
//DATA BIND/START - NOT UPDATING CHART
d3.selectAll("bubbleChart")
.data(data)
.enter().append("bubbleChart")
.attr("text", function (d) { return d.text; })
.attr("count", function (d) { return d.count; });
//DAT BIND/END
});
var bubbleChart = new d3.svg.BubbleChart({
supportResponsive: true,
size: 600,
innerRadius: 600 / 3.5,
radiusMin: 50,
data: {
items: [
{ text: "aaa", count: "236" },
{ text: "bbb", count: "382" },
{ text: "ccc", count: "170" },
{ text: "ddd", count: "123" },
{ text: kk, count: ll}
],
eval: function (item) { return item.count; },
classed: function (item) { return item.text.split(" ").join(""); }
},
plugins: [
{
name: "central-click",
options: {
text: "(See more detail)",
style: {
"font-size": "12px",
"font-style": "italic",
"font-family": "Source Sans Pro, sans-serif",
"text-anchor": "middle",
"fill": "white"
},
attr: { dy: "65px" },
centralClick: function () {
alert("Here is more details!!");
}
}
},
{
name: "lines",
options: {
format: [
{// Line #0
textField: "count",
classed: { count: true },
style: {
"font-size": "28px",
"font-family": "Source Sans Pro, sans-serif",
"text-anchor": "middle",

},
attr: {
dy: "0px",

y: function (d) { return d.cy; }
}
},
{// Line #1

classed: { text: true },
style: {
"font-size": "14px",
"font-family": "Source Sans Pro, sans-serif",
"text-anchor": "middle",

},
attr: {
dy: "20px",
x: function (d) { return d.cx; },
y: function (d) { return d.cy; }
}
}
],
centralFormat: [
{// Line #0

},
{// Line #1
style: { "font-size": "30px" },

}
]
}
}]
});
});
function formatItem(item)
{
return 'text:' + item.text + ', count:' + item.count;
}
