我在 Miktex+Texmaker 中有以下程式碼,使用設定 LaTeX+dvips+ps2pdf+View PDF:
下面第一張圖(fig:cosine-plot
)清晰可見:
\begin{figure}[H]
\centering
\begin{pspicture}(-2,-1.5)(4,1.5)
\psaxes{->}(0,0)(-2,-1.5)(4,1.5)[$x$,0][$y$,90]
\psplot[linecolor=red, algebraic]{-2}{3.5}{cos(x)}
\end{pspicture}
\caption{Plot of $\cos(x)$}
\label{fig:cosine-plot}
\end{figure}
然而,下面的第二張圖(Fig-sin-cos
)並沒有出現在編譯中。
\begin{figure}[H]
\centering
\begin{pspicture}(-2,-1.5)(4,1.5)
\psgrid[griddots=10,gridlabels=0pt, subgriddiv=0, gridcolor=black!20]
\psaxes{->}(0,0)(-2,-1.5)(4,1.5)
\psplot[linecolor=blue]{-2}{4}{sin(x)}
\psplot[linecolor=red]{-2}{4}{cos(x)}
\end{pspicture}
\caption{Graphs of $\sin(x)$ and $\cos(x)$}\label{Fig-sin-cos}
\end{figure}
\sin(x)
請幫我繪製和的第二張圖\cos(x)
。

您需要這個選項algebraic
,您可以在全球範圍內進行\psset{algebraic}
\documentclass[11pt]{article}
\usepackage{pst-all}
\begin{document}
\psset{algebraic} %change
\begin{figure}[ht]
\centering
\begin{pspicture}(-2,-1.5)(4,1.5)
\psgrid[griddots=10,gridlabels=0pt, subgriddiv=0, gridcolor=black!20]
\psaxes{->}(0,0)(-2,-1.5)(4,1.5)
\psplot[linecolor=blue]{-2}{4}{sin(x)}
\psplot[linecolor=red]{-2}{4}{cos(x)}
\end{pspicture}
\caption{Graphs of $\sin(x)$ and $\cos(x)$}\label{Fig-sin-cos}
\end{figure}
\end{document}
