Graphics, Figures & Tables ⇒ PSTricks error, why?

[timppapoika]

I'm starting to lose my mind here! Although LaTeX is very versatile, it sometimes can be be a pain in the ass! Now I'm trying to plot graph using the Least Square Method with pstricks-add and I've encountered a weird problem. I took the code from an example, but LaTex says:

Code: Select all

!Missing number treated as zero.
<to be read again>
                \def
l.283 \listplot
                [plotstyle=dots]{\data}
? h
A number should have been here; I inserted '0'.

Here's the code:

Code: Select all

\psset{lly=-.5cm} 
\readdata{\data}{LSM.data} 
\begin{psgraph}[arrows=->](0,0)(0,0)(8,8){.5\textwidth} 
\listplot[plotstyle=dots]{\data}
\listplot[plotstyle=LSM,linecolor=red]{\data}
\end{psgraph} 

I've set the data in the premble.

Can somebody help? My report is due wednesday, and the graphs are the only things left.

Please take care of your language and choose more appropriate words next time.

Attach the file LSM.data to your next post to make the problem comprehensible.

Is "butt" more appropriate?

Anyways, the LMS.data looks like this:

Code: Select all

\begin{filecontents*}{LSM.data} 
0 1 1 3 2.8 4 3 2.9 2 5 4 4 5 5.5 6 8.2 8 7 
\end{filecontents*} 

As I said I took the code from an example, which can be found on page 112 in http://www.ctan.org/tex-archive/graphic ... dd-doc.pdf

Your code misses the second mandatory argument for vertical size to the psgraph environment as described in the example from the pstricks-add manual.

Code: Select all

\begin{filecontents*}{LSM.data}
  0 1 1 3 2.8 4 3 2.9 2 5 4 4 5 5.5 6 8.2 8 7
\end{filecontents*}
\psset{lly=-.5cm}
\readdata{\data}{LSM.data}
\begin{psgraph}[arrows=->](0,0)(0,0)(8,8){.5\textwidth}{!}
  \listplot[plotstyle=dots]{\data}
  \listplot[plotstyle=LSM,linecolor=red]{\data}
\end{psgraph}

Thanks for the reply, localghost!

Adding the second argument for lenght of the y-axis results in a different error:

Code: Select all

!Undefined control sequence.
<recently read> \c@lor@to@ps

l.284 ...rrows=->}(0,0)(0,0)(8,8){.5\textwidth}{!}

I tried substituting the last two arguments to {10cm} and {5cm}, but the same error popped up.

Take a look at item #5 in the list of frequently done errors on the homepage of PSTricks.
