【问题描述】:
我的代码:
function d3_chart() {
// sample data array
// instantiate d3plus
var visualization = d3plus.viz()
.container("#viz") // container DIV to hold the visualization
.data("./extra/acc.csv", {"filetype": "csv"}) // data to use with the visualization
.type("line") // visualization type
.y("x") // key to use for y-axis
.x("timestamp") // key to use for x-axis
.draw() // finally, draw the visualization!
}
我的 csv:
timestamp,x,y,z

我刚刚收到消息: 无可用数据
怎么了?我在互联网上找不到任何通过这个库加载 csv 的示例
或者知道如何通过普通 D3 从 csv 中通过简单示例绘制图表?
【问题讨论】:
-
使用了哪个版本的 d3?
-
d3plus 有自己的 d3 版本:
