Question

我正在尝试使用visNetwork绘制网络。但是，没有显示边缘。 stackoverflow中有一个非常类似的问题。但那里提到的解决方案并不适用于我的情况。任何帮助都会很棒。以下是需要绘制的节点和边数据集。

why doesn't this visNetwork in R show edge

nodes_CTP

   ID         label
1   0         order
2   1       details
3   2           tab
4   3      displays
5   4       profile
6   5        window
7   6        status
8   7          sign
9   8   powerorders
10  9        detail
11 10        button
12 11  prerequisite

library(visNetwork)

 visNetwork(nodes_CTP, links_CTP, height = "700px", width = "100%") %>%
  visOptions(selectedBy = "label", 
         highlightNearest = TRUE, 
         nodesIdSelection = TRUE) %>%
  visPhysics(stabilization = FALSE)

Answer 1

这对我来说很好。验证数据格式（类和名称）。

def question1(request):
    question_form = QuestionForm()
    if request.method == 'POST':
        form = QuestionForm(request.POST)
        if form.is_valid():
            return render(request, 'music.questions2,html')
    return render(request, 'music/question1.html', locals())

visNetwork边缘未显示
