Graphics, Figures & Tables ⇒ PSTricks | Setting logarithmic Axes

[argan]

Hi,

I have a figure where the data points for the X-interval are in the interval [0.02 1], and I wish to plot this in a log-log plot. From the documentation, I understand that setting the origin of the axes in the psaxes options is done as e.g.

Code: Select all

psaxes[... Ox = -1, Oy = -1]

if I want to have origin of X and Y at 1e-1. But how do I do it if I want the plot to start at 0.02? I find no mention of this.

I suggest to take a look at the manual of the pst-plot package. And for an adequate problem description you should provide a minimal example. It will increase your chance for good and fast answers significantly.

Hi,

The documentation doesn't really say anything related to this. I'll try to provide som kind on MWE.

Thanks

Au contraire. The manual does this very well. See Section 9.20 for details and examples.

Hi,

I've looked at this section and not found anything really related to my problem. All I want is to set the origin of the x-axis to 0.02 (not 0.01) with the Ox command. But the only thing I find related to this is that to set it to 0.01, I use Ox = -2, because 1e-2 is 0.01.

What about preparing the minimal example you have already been asked for? Just in case you are interested in specific help instead of random shots.

Sorry for the time it took, but here it is:

Code: Select all

\documentclass[a4paper,11pt]{article}
% define the title
\author{B.~Fallqvist}
\title{MWE}\usepackage{graphicx,float,amssymb,dblfloatfix}
\usepackage[fleqn]{amsmath}
\usepackage{pstricks,pst-plot,pstricks-add,pst-grad,pst-node,pst-tree}
\begin{document}
\newcommand{\testnumbers}{
0.02 0.1
0.1 1
1 10
10 100}
\begin{titlepage}
% generates the title
\maketitle
% insert the table of contents
\end{titlepage}
\newpage
\section{MWE}
\begin{figure*}
	\centering
	\psset{xunit=3.6cm,yunit=1.0cm}	
		\begin{pspicture}(0,-1)(-2,2)
		\pstScalePoints(1,1){log}{log}
			\listplot[linecolor=blue,linewidth=0.5pt]{\testnumbers}
			\psaxes[subticks=10,axesstyle=frame,xylogBase=10,logLines=all,ticksize=5pt,tickstyle=inner,linewidth=0.5pt,Ox=-2,Oy=-1]{->}(-2,-1)(1,2)																	
		\end{pspicture}
\end{figure*}
\end{document}

Now, all I want to do is set the x-axis to start where the line starts, that is at 0.02 instead of 0.01. How do I do that?

Thanks
