Document Classes ⇒ No image - PStricks

[sveioen]

Is there a way to make PStricks understand what values the lower left and the upper right of the picture is by itself?

Code: Select all

\begin{pspicture}(x0,y0)(x1,y1)

The hardest work is sometimes just to make the "picture object" the right size so it fits with the actual graphic in it. There must be an easier way?

If this process is too hard or too inconvenient for you, take a look at the pgf/tikZ package. But specifying the size of a pstricks picture is not so complicated that such an automatism is needed. The showgrid option of the pspicture environment can always be helpful.

Code: Select all

\begin{pspicture}[showgrid=true](-3,-1)(3,3)
  …
\end{pspicture}

Once again localghost, thank you.
That will sure make it easier!

Take a look at the documentation of the pst-func package (Section 6.3 - Poisson Distribution, p. 24ff).

Trying to use this function, but I only get the error

Code: Select all

Undefined control sequence: \psPoisson

I have added the pst-func package.

You should get used to updating your LaTeX distribution in regular terms. Packages like pst-func are under continuous development. The \psPoisson command has not always been a part of the pst-func package. It was implemented in a later version, exactly in version 0.48 from March 17th 2007. So make sure you are using the current version (in this case 0.50) to get things work.

Does anyone know how this expression (Poisson distribution) is expressed with RPN? (need it in RPN form to plot in PStricks)

[url]http://www.matematikk.net/cgi-bin/mimetex.cgi?F(x)%20=%20\frac{e^{-0.68}*0.68^{x}}{x!}[/url]

F(x) = \frac{e^{-0.68}*0.68^{x}}{x!}




And by the way, this forum should really have TeX support

Another way of getting RPN from infix is to use the infix-RPN package.

[balfonsi]

With the 'algebraic' option of pstricks-add, you don't need to use RPN notation any more with pst-plot.

B.A.

[hubert]

True. However when you plot graphs and want to refer to a function value directly, you still need RPN for the "(! )" (\SpecialCoor) statements.

Hence my own learning path (only started this year!) was to use infix-RPN, place a \RPN somewhere and learn how to translate between infix & RPN myself.
