Mathscript print command????

[Clueless1]

Help.

I need this command or equivalent work around.  For instance, can I programatically print mathscript figure windows using LV picture programming?

Thanks

Hi Clueless,

what do you wanna print?
The front panel or the block diagram?

-You can set vis to print the front panel when finishing execution.
-You can print the front panel by calling a method node.
-You can save the front panel to PNG file (or other graphics format).
-You can use the excellent CodeCaptureTool.

Does it answer your question?

I'm using LV 8.5.

I want to print the figure window generated when I have a mathscript window that has for instance the following lintw

figure
plot(fft(eye(37)))

I would like to print the picture programatically in "mathscript".  But alas, there is no print command as in M#TL#B.  So, is there a way to get a reference to the graphics window the pops up in response to a mathscript "figure" function.  I can print the window using pointNclickery but have not found a way to automate this task.

Thanks,

Howard

Hi Clueless,

you're talking about the "Mathscript window" you can call via tools menu?

I don't see any option to print this programmatically as this tool is mainly intended for "trying-out before programmming".
When you finish your testing you can save the mathscript program to a file and use it in a "real" vi. Here you can use the options told above for printing (and you can even make nicer plots)...

No,  I'm talking about a mathscript window (Structure?) that's inside a LV picture program.  You don't have to use the mathscript IDE to generate a figure window.

Hi Clueless,

so you're talking about the "mathscript node"

IMHO:
The mathscript "figure" command is creating the window to show the plot. You cannot (easily?) get the window reference as this is maintained by the mathscript node. It's like not getting intermediate results when mathscript is calculating numbers - it's all inside that node...
To have a reference for printing you should create your own windows or use the front panel of the vi running the mathscript node!

"To have a reference for printing you should create your own windows or use the front panel of the vi running the mathscript node!"

Are  you saying that I can plot mathscript "node"  figures onto a LV front panel?  How?

How do I create my own windows, and can I pass a reference to them into a mathscript node that I can then plot stuff into??

Thanks

Hi clueless,

I haven't worked with MatLab for long, so I only know some basics:
Use "a=fft(eye(37))" instead of "plot(fft(eye(37)))".
Set a as output of the mathscript node, it will be some kind of array (2d probably).
Wire this to a xy-graph (split the array into x- and y-array, build cluster as in context help for xy-graph).
Now you have a xy-plot on your front panel and you may print the front panel as you like...

Has anyone got an answer?

Why is the picture plots - "plot multixy such a travesty?  The defaults are ugly.  Why doesn't the default look as good as the matlab style plot that's easy as typing

figure
plot(x,y1,x-)
hold on
plot(x,y2,o-)

title('mytitle')
xlabel('myxlabel')
ylabel('myylabel')
legend('y1','y2')

I've screwed around with it for hours and can't get anything even close to publication quality.

Hi Clueless,

it's maybe because LabView is a graphical programming language whereas MatLab is text based?

All of those options can be set by property nodes or (at development time) in the properties dialog of the plot...

And you already mix up names: do you use "picture indicator" or "xy-graphs" or "waveform-graphs" or "waveform-charts"?
