I think you can use "textplot" command  for your purpose.

Your first line, under the command with(plots): has an error in the range.

p1:=plot(sin(x),x=-2*Pi...2*Pi,tickmarks=[0,0],color=black):

should be

p1:=plot(sin(x),x=-2*Pi..2*Pi,tickmarks=[0,0],color=black):

You have an extra dot between -2*Pi and 2*Pi.  I do not know if this will fix anything, but it does not help.

Later edit.  This does not matter.  It will not fix the LaTeX issue.

For your textplot question, here is an example that you can modify for your own use. 

restart:
with(plots):
p := plot(sin(x), x = -2*Pi .. 2*Pi, tickmarks = [0, 0], color = black):
t1 := textplot([4*Pi*(1/3)+1, 1, typeset(''y = 2*cos((1/2)*x-(1/6)*Pi)'')], align = above):
t2 := textplot([5, .5, typeset(''y = 2*cos(x/(2*Pi))'')], align = above):
display({p, t1, t2});

You can play with the location values to align the equation wherever you want it.

The above will not work with the Classic V12 interface.  Only with the Standard interface.

Can't you get the first plot with a single plot command?

plot( sin(x), x=-2*Pi..2*Pi, color=black, tickmarks=[spacing(Pi/2,0),3] );

You will have, in general, better success with math expressions in plot captions, etc., if you use the typesetting capabilities built-in to plot. For example,

plot( 2*cos(x/2-Pi/6), x=-2*Pi..2*Pi,
      tickmarks=[spacing(Pi/2,0),3],
      title=typeset("A plot of one period of \n", y=2*cos(x/2-Pi/6)) );

As far as creating plots for use in LaTeX, my current process is to manually export the plot to a GIF or JPEG file, then convert each image to a PDF file, which can now be brought into my (pdf)LaTeX documents. (The exporting to a file can be automated using plotsetup.

I think you'll have much more success with this approach.

The real reason you're seeing the difference in the titles is because of standard and extended typesetting. The plot system currently uses standard typesetting, even when the user changes the default to extended. However, the call to Typesetting[Typeset] generates the extended typesetting output. We hope to resolve some of these standard/extended typesetting issues in the future. In the meantime, you can use Typesetting[Typeset] to achieve the desired result, but it's one of those "use at your own risk" routines. It's meant to be an internal undocumented routine, but there is some information about it on the Typesetting help page, as it can be useful to users in some cases.

If you are not restricted to generating all parts of the plot programmatically and can adjust it interactively, then the easiest way to get the desired title is to edit the title in place using the context menu.

Doug writes: "I agree that the context menus are the easiest way to customize a plot, but I wish there was a way to get Maple to return the command needed to (re)produce the plot from the command line. This seems like it should not be too difficult to achieve. What are the chances it could appear in the near future?"

For the very near future, I don't think the chances of getting this feature are good. In general, plots can be created through a combination of library commands, context-menu actions and drag-and-drop actions. For anything other than the most simple cases, I'd think it would be difficult to recover a library command to generate an arbitrary plot.

However, in the long term, there may be other features that will make it easier to keep track of changing options in plots. As some of you have noticed, there have been steady improvements in plots over the past few releases. I expect that making plots better and easier to use will continue to be a priority in the future.

Paulina

There are different questions being asked here. The one that Doug asked was, "Can I get a Maple command that reproduces a particular plot that might have undergone context-menu changes?" Another question is, "How do I keep track of context-menu actions I've made?" Other questions not explicitly asked, but which I assume are of interest, are "Can I get a library command that corresponds to a context-menu action?" (slightly different from the first question) and "How do I keep track of current option values?"

I was responding to the first question from Doug about retrieving a plot command. I don't see this feature appearing in the very near future, but I wouldn't go so far as to call it an "impossibility".  However, it may be more useful to provide, in future releases, better ways of keeping track of current plot option values and setting defaults that can be applied to multiple plots. We do have the plots[setoptions] command right now, but it has some limitations.

Hi all. 

It is still not giving what I want.

I am using the Classic Worksheet Maple 12 and here's my code:

> restart;
> with(plots):

> p6:=textplot([[4*Pi/3+1,1,`y=2cos(x/2-Pi/6)`],[Pi-0.5,-1,`y=2cos (x/2)`]]):
> display({p1,p2,p3,p4,p5,p6});

The graph plotted beautifully.   The plot is to show y=2cos(x/2-Pi/6) is merely a shift of y=2cos(x/2) with period 4Pi, displacement Pi/3, limits -2 and 2 and the graph starting at Pi/3 and ending at 13Pi/3.  The only downfall was that Pi was not outputted as a symbolic form in the plot.  It just gave y=2cos(x/2-Pi/6) instead of giving the symbol Pi where appropriate. 

Maple should design the software such that the commands that works in Maple 12 should also work in the Classic Worksheet as well. 

Agreed.  I have been vocal about your concerns in this forum for a long time.  A while ago I addressed this issue with a workaround using textplot.  It is rather painful in that you have to figure out exactly where to place the symbol,  but if you "must" have the  symbolic version, you can do it.  See a previous thread here.

Paulina, thanks for your input.  I use Standard Interface with 1-d math.  Having two different interfaces adds confusion.  How about 1 interface, with a toggle mode to go between 1-d and 2-d.  That way you have the best of both worlds.  As you can see from the questions that users are posting here, this item comes up on a regular basis.  Either have all of the features available in Classic, or do away with it completely, and offer a seamless method to switch between modes for legacy users and new users who do not care about 1-d math mode.

Dear all,

Thanks for all the input/output, especially Georgios Kokovidis!   3 cheers to you!  :)

The thread was extremely helpful.  I am now able to insert "Pi" into my Maple 12 Classic Worksheet now. 

Here is the code to share around (if you are interested):

I have shrink the picture a tad as well. 

Unfortunately, this code will not work on the normal Maple worksheet (non classic).   It keeps complaining about an error with p5 (which is the pointplot). 
"Error, (in plots:-display) expecting plot structures but received: {plots:-pointplot*([[(1/3)*Pi, 0], [(4/3)*Pi, 0], [(7/3)*Pi, 0], [(10/3)*Pi, 0], [(13/3)*Pi, 0], [2*Pi, 0], [3*Pi, 0], [4*Pi, 0], [0, 2], [0, -2]], symbol = CROSS)}"

From this, I have learned:

(1) "Classic Worksheet Maple 12" is not compatible with "Maple 12".  That shouldn't be the case!   If it works in Classic Worksheet, it should also work in the normal worksheet.
(2) When the plot is done, I right clicked on the plot, go to "Export As" , choose "Encapsulated Postscript (EPS)" and save it as a eps file.  Problems then arises when trying to embed this eps file into LaTeX with the usual begin{figure}, etc.  Problem 1: The plot is rotated anti clockwise by 90 degrees.  Problem 2: Whenever there is a minus sign in front of some Pi symbols, Maple converts it  to "plus or minus" signs -- the \pm sign if you use LaTeX.   See my second post. 

Hopefully, developers of Maple will do some changes to tackle these problems for the new release.  We don't want Maple to be like another "you know who" suite where problems just rolled over.

Georgios, I do agree with you that the two interfaces can be confusing. However, some users still need to use Classic if their machines don't have enough memory to support Standard. For users who don't have this problem, I recommend switching to Standard. Some people just prefer to stay with Classic because of the faster response time. Fair enough ... but you have to give up a lot of new features when you do that. it really depends on what your Maple needs are.

As pagan points out, it is possible to easily toggle between 1-d and 2-d input modes in the Standard worksheet, so the new input mode should not be a barrier to using the Standard worksheet.

I know there are mixed opinions about 2-d input, but my personal feeling is that both 1-d and 2-d input modes are useful. There are different circumstances in which one or the other is better suited to the task, and in the Standard worksheet, you can use both.

Paulina

Hi Paulina.  Thanks for the advice.

I have made the appropriate changes (getting rid of the extra space) and now it works on the Standard worksheet as well as the Classic Worksheet.

However, my point number 2 still stands -- regarding the EPS file and LaTeX problem.   The problem should not be happening -- with the changes to the "plus/minus" signs and the rotation.

To get around it, I had to copy the graph from Maple and paste it into Adobe Illustrator CS3 and then save it as a EPS file.  This is a pain but it is a temporary fix.

Chris

Hi Alec.  I had to use it -- no choice.  I tried exporting the Maple plot to an EPS file and then integrating it into LaTeX.  And I got the problem (see "The concluding saga to: "How to plot" with success! ")   I thought my command in LaTeX was wrong, so I opened the EPS file by itself and it gave the same dreadful plot (which was wrong).

So copying the Maple plot and pasting it into Adobe Illustrator CS3 and then saving it as a EPS file was the only quick fix that I came up with......unless Paulina could come up with something better?????

Hi Alec. I don't need the whole worksheet to be converted.  Just the plots.  Yes, I have done this before in previous versions of Maple and had no problems with it. 

Why don't you try it yourself with the new Classic Worksheet Maple 12? 

Here's the code for a SIMPLE sine graph:

> restart;
> with(plots):
> p1:=plot(sin(x),x=-2*Pi..2*Pi,tickmarks=[0,0],color=black):
> p2 := textplot([[Pi,-0.05,`p`], [Pi/2,-0.05,`p/2`],[-Pi/2,-0.05,`-p/2`], [-Pi,-0.05,`-p`],[0.2,-0.05,`0`],[-3*Pi/2,-0.05,`-3p/2`],[-2*Pi,-0.05,`-2p`],[3*Pi/2,-0.05,`3p/2`],[2*Pi,-0.05,`2p`]], align=below, font=[SYMBOL,10]):
> p3 := textplot([[-0.1,1.0,`1`], [-0.1,-1.0,`-1`],[-0.1,0.5,`y`],[2*Pi+1.5,-0.05,`x`]],align=left):
> p4:= pointplot([[-Pi,0], [-Pi/2,0], [Pi/2,0],[Pi,0],[0,1.0],[0,-1.0],[-3*Pi/2,0],[-2*Pi,0],[3*Pi/2,0],[2*Pi,0]], symbol=CROSS):
> display({p1,p2,p3,p4});
 

Once the graph is plotted, right click on it, then choose "Export As" and then "Encapsulated Postscript (EPS)".  Then try opening this file with extension eps or try putting it into your normal LaTeX code (I used \begin{figure},etc).  You will see what I mean in the negative x axis.

All are welcomed to try this code and see if it happens to you?!    Paulina --- if you could please try this, it would be greatly appreciated.

BTW, what is this "point system"?  Everytime I post a new post, I get 1 point.  What does these points enable you to do? 

Chris

Move your mouse pointer over the number that is next to your name, and click.  An explanation will follow.

Hi Acer.  Thanks for the suggestion.

A space after the negative sign and before 3Pi/2 helps!

Also, the additional code which immediately transform the output to a eps file is great!  *thumbs up*

I embed the eps file into LaTeX and then convert the DVI file to PDF and use Adobe Acrobat 9 to view the result.

What kind of software would you use if I were to plot the graphs found in The concluding saga to: "How to plot" with success! and EPS and LaTeX (III) with the required tickmarks and text minus the hassles?  :)

Hi Acer. 

I used

plotsetup(ps,plotoutput=`foo.eps`,plotoptions=`portrait,noborder`);

as suggested by you.

Unfortunately, the removal of the space in `-3 Pi/2` and `-2 Pi` (using Maple 12 Classic Worksheet) still results in a plus/minus sign when viewed in Ghostview 4.9.  Using Adobe Illustrator CS3, it becomes a small empty little box instead of a negative sign.

kris2099, I'm not that knowledgeable about how plot exports work but I'll see if one of my colleagues can shed some light on this matter. (I maintain many of the library plotting commands but a large part of the plotting system is maintained by my colleagues in the GUI Group). You might not get an answer right away though. Not all of us read MaplePrimes on the weekend. :-)
