我有两个不同的图表使用相同的精确数据。一个使用嵌入在html中的json，另一个则读取文件。
我一直在google上寻找anychart读取json文件或web服务的例子。我什么也没找到。
由于第二个图表使用json调用读取d3.json数据，我想也许可以使用相同的函数读取anychart图表中的数据。
所以我把两个图表的javascript都包括在内。anychart javascript：
<script type="text/javascript">
anychart.onDocumentReady(function() {
chart = anychart.fromJson(
{chart: {type: "line",
series:[{seriesType: "spline",
data: [{x: "January", value: 10000},{x: "February", value: 12000},{x: "March", value: 18000}]}],
container: "container"}}
).draw();
});
</script>
d3从json文件读取。也许我可以使用这个调用在前面的代码中填充报表？:d3.json("data.json", function(error, data) {
var nest = d3.nest()
.key(function(d) {
return d.date;
})
.map(data);
rect.filter(function(d) {
return ("$" + d) in nest;
})
.attr("fill", function(d) {
return color(nest[("$" + d)][0].open);
})
});
如有任何帮助，我们将不胜感激。我只想知道这是否可能。

有https://api.anychart.com/7.13.1/anychart.data#loadJsonFile和https://api.anychart.com/7.13.1/anychart#fromJsonFile方法，它们是数据适配器脚本的一部分。
