As far as I recall, eps export produced good quality plots (if they didn't include text) in old Maple versions, something like Maple V and Maple 6. However, there were still some bugs in it - in particular, with the bounding box. They could be easily corrected manually though.

Sometime around Maple 8 or Maple 9 eps export was changed to produce the same poor quality plots as in other graphics formats, so it seems to be not usable at the moment.

Some people print plot structures to a file (if possible) and then use some other graphics tools to produce publishing quality plots. But it is more simple just use other CAS - such as SAGE (which is free), or Mathematica, or Matlab.

Try

plotsetup('ps','plotoutput'="plot.ps",'plotoptions'="portrait,noborder");
plot(x^2,x=-1..2);

I don't see any of the jaggies that you mentioned.

Although Maple did make noble progress with the ability to put math symbols in a graph to be exported to eps, I still find it far inferior to what I used to be able to do with the LaTeX psfrag package.

The "classic" plot format along with textplot would allow one to place text markers in the eps file that psfrag could mark up according LaTeX code. That allowed something close to publication quality. 

But now the bloated Maple eps file does not afford this technique--Maple's new eps format is not compatible with psfrag.

Hi there,

The two Maple/eps files you posted look good on my system (both the ps and pdf), and publishable. The output you obtain in your own myplot.pdf does not look like the kind of plot generated by Maple, Matlab,  or Mathematica, in my experience at least.

Here is what I do. It may not be good enough for your standard, but just in case:

I use Maple classic. In addition I show below how I define some colors (blue, red, green) to substitute the standard Maple colors. You can control line thickness, the grid size, the appearance of ticks, of labels, and many other things.

> display({p1,p2,p3},labels=[``,``],axesfonts,labelfonts);
> plotsetup(ps,plotoutput=`theplot.ps`,plotoptions=`color,portrait,noborder,axiswidth=400pt,axisheight=400`): display({p1,p2,p3},labels=[``,``],axesfonts); plotsetup(default):

Having produced a ps file of my basic graphic, I then use pstricks to produce a proper eps format that LaTeX can read, with labels, arrows, titles, etc.

Here is a LaTeX file to do that:

\documentclass{article}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{graphicx}
\usepackage{pstricks}
\pagestyle{empty}

\usepackage{color}
\definecolor{webgreen}{rgb}{0,.5,0}
\definecolor{webblue}{rgb}{0.1,0,0.55}
\definecolor{webred}{rgb}{0.9,0.1,0}

\begin{document}

\begin{center}
\begin{pspicture}(0,0)(\textwidth,\textheight)
%\psgrid[gridcolor=blue,griddots=10,subgriddiv=2,subgriddots=10,subgridcolor=gray,gridlabelcolor=blue,gridlabels=7pt]
\rput[lb](0,0){\includegraphics[width=\textwidth]{theplot}}
\rput[r](6,12.5){$f(x)$}
\rput[l](12.5,0){$x$}
\end{pspicture}
\end{center}

\end{document}

I find the output to be good enough for my needs. Just as I find the files you have updated to look quite good on my system.

I'm using windows. Is there a problem with your drivers or are your needs very advanced?
