Question

利用dygraph javascript的硬件是嵌入式PIC24FJ64GB004，配置为数据记录器和大容量存储设备，拇指驱动器。从USB上拔下它将9轴惯性数据：加速度，角速度和磁力计记录到根驱动器上作为.csv文件。当插入USB端口时，批处理文件使用dygraph javascript将数据解析为可用于.html显示的位置的文本文件。

系统在WINXP SP3中正常运行但未能在未来版本的Windows中显示数据。

利用F12开发人员工具我得知文本文件在WINXP中没有很好地形成，但在Windows 10中 - F12声明如下：

dygraph-combined.js:2 XMLHttpRequest cannot load file:///C:/Users/Cal/Desktop/ER9D0F/Temp/Graph/data/accelerate.txt. Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https, chrome-extension-resource.Dygraph.start_ @ dygraph-combined.js:2

的Util

问题：为什么两个操作系统之间存在差异？ .net版本是个问题吗？是否有更详细的数据格式描述？

谢谢 Cy Drollinger

Answer 1

我已将数据解析为data.js，例如示例中使用的data.js文件：temperature-sf-ny.html。与示例一样，函数加速被调用。 data.js看起来像这样：

function accelerate() {
 return "" +
"Time,X,Y,Z\n" +
"0.00,0.10508,0.51271,1.29130\n" +
"0.01,0.09091,0.47410,1.20039\n" +
"0.02,0.06158,0.42815,1.04545\n" +
"0.03,0.03715,0.38856,0.88465\n" +
"0.04,0.01711,0.33920,0.73705\n" +
"0.05,-0.07234,0.33920,0.65445\n" +
"0.06,-0.12366,0.34702,0.66373\n" +
"0.07,-0.14809,0.40860,0.74487\n" +
"0.08,-0.18377,0.43842,0.83627\n" +
"0.09,-0.18328,0.41740,0.86706\n" +
"0.10,-0.15152,0.39638,0.92180\n" +
"0.11,-0.08944,0.38905,1.00440\n" +

虽然这没有回答这个问题，但它确实让我得到了我需要的地方。索引页面上的快速链接中有更详细的数据组件描述：数据格式。

在WIN7及更高版本中没有绘制Dygraph数据？
