Intento usar xpf, pero no funciona en este caso. ¿Cómo trazar este gráfico?

Answer 1

Con tu código no obtengo el aviso (es un aviso, no un error).

Su mensaje de advertencia contienePaquete pgfplots Advertencia: (...) en la línea de entrada 464., pero no tenemos 464 (o más) líneas en su código (solo 80 líneas).

Si creo su archivo con el nombre solution_a=5_n=1.csv(y suprimo las 3 líneas con solo "." en lugar de dos números separados por comas, consulte el extracto a continuación)

1.03,0.03081619467761404

4.910000000000004,0.7971864038672304

o si agrego:

\begin{filecontents}{solution_a=5_n=1.csv}
x,y
0.0,0.0
0.01,0.00010774053043701307

5.200000000000004,1.4148106903997526
\end{filecontents}

en el preámbulo (tenga en cuenta que \usepackage{filecontents}ya no es necesario en las instalaciones modernas de LaTeX)

y corrijo algunos errores tipográficos ( \begin{figure}[h]agregué lo que faltaba \y lo reemplacé ytick={0, 0.2, 0.4; 0.6; 0.8; 1.0; 1.2},por ytick={0, 0.2, 0.4, 0.6, 0.8, 1.0, 1.2},lo que necesita ,en lugar de ;),

el archivo se compila sin errores:

Entonces, con el código que proporcionaste y las correcciones que dije, la advertencia desapareció (pero el trazado no es lo que esperabas ya que faltan coordenadas de x=1.04 a x=4.90, por lo que el espacio está limitado con una línea recta). línea).

También hay otra advertencia con el código que proporcionaste:Advertencia de LaTeX: opciones globales no utilizadas: [informe].Es el reporten \documentclass[12pt,a4paper,report]{extarticle}. No conozco esta opción global, qué paquete la usa.

Échale también un vistazo aGráfico de barras de pgfplots: la coordenada x simbólica única da como resultado "! Paquete pgfplots Advertencia: el rango del eje x está aproximadamente vacío; agrandándolo".
