Question

我有以下数据：

<rect fill="green" width="0.0000028312475887345677"
    x="-0.0000014156237943672838" height="81.66666666666667" y="0">  
</rect>

我正在尝试使用Plottable.Plot.Rectangle创建一个热图，其代码如下：

    //get video byte[], tested that it doesn't lose metadata uploading 360 photo
    RandomAccessFile f = new RandomAccessFile(file.getAbsolutePath(), "r");
    byte[] b = new byte[(int)f.length()];
    f.read(b);

    //set upload params
    Bundle params = new Bundle();
    params.putByteArray("video.mp4", b);
    params.putString("title", file.getName());

    //create and init request
    GraphRequest graphRequest =
        new GraphRequest(
            AccessToken.getCurrentAccessToken(),
            "me/videos",
            params,
            HttpMethod.POST,
            new GraphRequest.Callback() {
              @Override
              public void onCompleted(GraphResponse response) {
                if(response.getRawResponse() == null){
                  Log.e("UploadServiceParentFB", "fail to upload");
                  showNotificationError(getResources().getString(R.string.no_permissions));
                }
                else {
                  file.delete();
                  showNotification();
                  Log.d("UploadServiceParentFB", "" + response.getRawResponse());
                }
              }
            });
    graphRequest.executeAndWait();

然而，它只是创建宽度为0的rects，因此某些东西在x轴（日期）上不起作用：

str = "a,b,c,d,e,f,g"
str = str .. ','
for w in str:gmatch("(.-),") do print(w) end

Answer 1

似乎你必须指定.x2（），例如

.x2(function (d) {
            return new Date().setHours(d.date.getHours() + 8);
}, xScale)

Plottable.Plots.Rectangle创建宽度为0的rects
