#julia #plotly-dash
Вопрос:
Адаптация второго примера из https://dash-julia.plotly.com/getting-started как показано ниже, я получаю ошибку StackOverflow. Является ли пример устаревшим или что-то не так с моим кодом или установкой?
Обратите внимание, что добавление рисунка в виде кортежа данных работает (закомментировано в примере кода), но использование структуры PlotlyJS.SyncPlot, возвращенной из plot, не работает. Я также могу отобразить рисунок в VSCode без каких-либо проблем.
using DataFrames, PlotlyJS
using Dash, DashHtmlComponents, DashCoreComponents
using Random
ydata = [rand() for i in 1:4]
app = dash()
app.layout = html_div() do
dcc_graph(
id="example-graph",
# figure = (data = [(y = ydata,)],) # Works
figure = plot(ydata) # Does not work
)
end
run_server(app, "0.0.0.0", debug=true)

Комментарии:
1. Можете ли вы добавить вывод об ошибке в свой вопрос?
2. Готово, спасибо, что посмотрели.
3. Не знаю, для меня это работает, так что я не могу точно проследить, что идет не так. Я думаю, вы уже проверили это, но в любом случае убедитесь, что ваши посылки обновлены. И может ли быть так, что
plotфункция также была импортирована из какого-то другого пакета, в результате чего нужная функция вообще не вызывается?4. Знание того, что код в порядке, — это большая помощь. Даже после переустановки Julia я, к сожалению, все равно получаю ту же ошибку. Функция построения графика, кажется, работает правильно, и я могу отобразить рисунок в vscode.
