Как исправить ошибку построения графика «Пакет pgfplots Предупреждение: Диапазон осей для оси y приблизительно пуст; увеличиваем его (он [0.0:0.0])»

Question

У меня есть файл .csv, например

Я пытаюсь использовать xpf, но в этом случае это не работает. Как построить этот график?

Answer 1

С вашим кодом я не получаю предупреждения (это предупреждение, а не ошибка).

Ваше сообщение предупреждение содержитПакет pgfplots Предупреждение: (...) на входной строке 464., но в вашем коде нет 464 (или более) строк (только 80 строк).

Если я создам ваш файл с именем solution_a=5_n=1.csv(и оставлю три строки только с "." вместо двух разделенных запятыми чисел, см. отрывок ниже)

1.03,0.03081619467761404
1.04,0.03141681742042154

4.900000000000003,0.7831223904577598
4.910000000000004,0.7971864038672304

или если я добавлю:

\begin{filecontents}{solution_a=5_n=1.csv}
x,y
0.0,0.0
0.01,0.00010774053043701307
(continue)
5.190000000000003,1.3845636938257693
5.200000000000004,1.4148106903997526
\end{filecontents}

в преамбуле (обратите внимание, что \usepackage{filecontents}в современных установках LaTeX это больше не требуется)

и я исправил некоторые опечатки (в \begin{figure}[h]я добавил отсутствующее \, и заменил ytick={0, 0.2, 0.4; 0.6; 0.8; 1.0; 1.2},на ytick={0, 0.2, 0.4, 0.6, 0.8, 1.0, 1.2},, как вам нужно, ,вместо ;),

файл компилируется без ошибок:

Итак, с предоставленным вами кодом и внесенными мною исправлениями предупреждение исчезло (но график не такой, как вы ожидаете, поскольку у вас отсутствуют координаты от x=1,04 до x=4,90, и поэтому разрыв ограничен прямой линией).

Также есть еще одно предупреждение с предоставленным вами кодом:Предупреждение LaTeX: неиспользуемые глобальные параметры: [report].Это reportin \documentclass[12pt,a4paper,report]{extarticle}. Я не знаю эту глобальную опцию, какой пакет ее использует.

Взгляните также нагистограмма pgfplots: одна символическая координата x приводит к результату "! Пакет pgfplots Предупреждение: Диапазон осей для оси x практически пуст; увеличиваем его".
