Oh my... I simply did not see that, sorry.

Thank you for the reply.

Happy new year to you Martin

I just tried your example file. It crashes my SMath, but never mind. I copied parts of your file into another one to see what causes the problem.

I just wanted to thank you for stats package. It seems it is working . The results are put in the system as you presented in your example.

Resizing of svg plot example is working for me as well. At the moment I do not know the details of it and how to use it for other plots using draw package, but never mind - I will figure it out sooner or later.

It seems that the problem and crash of SMath appeared just at the beginning of your example (linearalgebra regions also did not produce output). I copied the regions and "stack empty" errors appeared sometimes, sometimes crash happened. It does not look that those regions should cause problems. Actually, only by disabling the calculation of the first two math regions in your example (these first two like in the picture will suppress the SMath crash - calling functions from linearalgebra will still fail).

See the picture and the log file please.

Regards,
Radovan

You are welcome

I see your point in the drawing with many options and a problem related to them. I am not that experienced with this, and to be honest I forgot them constantly. It is impossible to memorize them. That is why we must have them available all the time.

At the moment just wanted to point out about the crashing problem of the few mentioned regions. If you have the patience just see these two videos.
Maxima crashes SMath
Debug - extra commas?

Or see the pictures, where I suppose might be a problem.

Here is a preview on how graphics could be supported in the Maxima plugin. In the attached sheet, the functions Draww2D() and Draw3D() are defined.
They take a list of options and objects as first argument, the output file name as second argument and optionally a two element list or matrix as size specification (defaults to 300x240 pixels).

Filenames can be given with .svg or .png extension, the output format is set accordingly. If no extension is given, it defaults to .svg. The functions return the actual name of the produced output.

For display, image regions are used. If the image region would evaluate the file name expression, the complete command for making the plot could reside in the placeholder and eventually be hidden. For now, the file name must be assigned to a variable and that variable must be put in the placeholder of the image region.

The attached sheet contains snapshot regions, as it was made to produce images for the pdf-handbook.

The examples in the attached sheet are mainly from the Maxima-Handbook, but also from the Plot3D plugin by uni (Klein bottle). The screenshots show the complete code required to produce the plots (except init like setting current dir to document directory and eventual reset of Maxima incl. loading of the draw package.

After some playing around and eventual feedback from the forum we shall implement the proposed functions in the Maxima plugin. Feel free to test and propose improvements.

Plugin updated.

- Adjustments to plugin interface changes
- bug fixes
- functions Draw2D() and Draw2D()
- improved messages on pos/neg assumptions
- xml settings file with options for customization

EDIT:
You might need to execute the example twice in order to get the image paths right. Is on the todo list.
The translation process is purely regexp based and slow, but more reliable than ever.
Plotting more than 200 points (if not Maxima-generated) is not recommended.

Don't worry, will be relased ASAP

Hello Martin,

It seems there is a bit unstability in Maxima plugin and the recent SMath nightly build. I used both on my Win7(x86) and Win7(64). On x86 performs better, but sometimes crashed when using Reference Notebook. If not crashed than [Maxima] no data availiable appered - see the picture pleas. On x64 it is much worse. I attached the logfile and your file. It crashes SMath. You can also see this on the video

Radovan

I just was a bit worried about the messages like "memory damaged ..." on my office comuputer and the crash things. Moreover Algsys() also can produce this problem like in this video. The problem is with Ans you defined in the Notebook. I just hope you are aware of all of this and those changes in SMath will not be so often in order to produce this behavior of Maxima plugin. Than would be almost impossible to keep Maxima plugin up to date

Regards,
Radovan

Hello Andrey,

I am not able to follow what changed - I am not a programmer. Actually, I was just thinking from the point of users and plugin makers. I remember uni mentioned that there is no definite agreement about the plugins (do not know what that actually means). I also remember there some time ago a similar situation when Extension Gallery was introduced. Plugin makers had to change the things. I do not how much time would take to stabilize the things regarding plugins. I hope I made myself understood.

Regards,
Radovan

Can the maxima plugin be used in Linux? I have maxima installed, but the maxima control window crashes when I try to open it
