Graphics, Figures & Tables ⇒ Incorrect graphs of Sine and Cosine and Axes problems

[coachbennett1981]

I posted a graph earlier, but I am having more difficulty. I am reading the PsTricks-Add documentation, but can't see to figure this out. Below are two graphs, both sin(x). The first graph is correct with correct labels, but the second graph is not. Notice the y value of pi. How can I have different labeled axis to match my function?

Code: Select all

\documentclass[12pt]{article}
\usepackage{pstricks-add}
\begin{document}

 \begin{pspicture}(-6.5,-7)(6.5,7.5) 
 \psaxes[trigLabelBase=3,dx=\psPiH, xunit=\psPi,trigLabels]{->}(0,0)(0,-4)(\psPiTwo,5)[$x$,0][$y$,90] 
 \psset{algebraic} 
  \psplot[yMaxValue=6,linewidth=1.6pt,plotpoints=2000, linecolor=red,arrows=<->]{0}{\psPiTwo}{sin(x)} 
  \end{pspicture}

 \begin{pspicture}(-6.5,-7)(6.5,7.5) 
 \psaxes[trigLabelBase=2,dx=\psPiH, xunit=\psPi,trigLabels]{->}(0,0)(0,-4)(\psPiTwo,5)[$x$,0][$y$,90] 
 \psset{algebraic} 
  \psplot[yMaxValue=6,linewidth=1.6pt,plotpoints=2000, linecolor=red,arrows=<->]{0}{\psPiTwo}{sin(x)} 
  \end{pspicture}
\end{document}

Again, I appreciate you taking the time to help. I know I ask alot of graphing questions that you respond to. I like to keep you guys on your toes

Herbert,

The graphs look great, but notice in the first set of code:

Code: Select all

\begin{pspicture}(-0.5,-1.5)(6.5,2)
\psaxes[trigLabelBase=3,xunit=\pstRadUnit,
  trigLabels]{->}(0,0)(0,-1)(\psPiTwo,2)[$x$,0][$y$,90]
\psset{algebraic}
  \psplot[linewidth=1.6pt,
  plotpoints=2000, linecolor=red,arrows=<->]{0}{\psPiTwo}{sin(x)}
\end{pspicture}

sin(pi)=0, however, the graph is slightly off the appropriate y value, is there anyway to fix this?

I cannot see any problem ...

You are right, I opened a new file and got the same graph. I am sorry to have troubled you again.. Thank you for you time.

Best,
