I am running a cluster analysis and want to plot some of my results in histograms. To compare one cluster with another I find it useful to use the same coordinate system and same bin width for each histogram. For the plot range I already got a tip:
PlotRange/.Options[Histogram[DeleteCases[Flatte...
I am trying to make a plot legend (and not use PlotLegends). What is the best format for including the legend in the plot and being able to position it either inside or outside the plot?
@Szabolcs I've tended to take a more manual approach... make the plot and legend as separate graphics, make a new graphic, and paste them in at the appropriate locations. I'm sure there are better ways (I even bought David Park's Presentations, but hardly used it), but it works well enough for me...
@Sjoerd then that's the reason (default is True; I guess you switched it off though because of problems exporting vector graphics with Mathematica2 font embedded?). You could switch it back on just in the $FrontEndSession though I guess.
@Szabolcs no, just in the front end. Apparently it's possible to do some decent drawings although I'm not sure exactly how to use most of the tools properly (check out the satellites example in ref/StateResponse... someone clearly made good use of the drawing tools).
@Sjoerd yeah, I didn't realise $FrontEnd options are persistent either until I answered @Szabolcs's question that reset the configured kernels and wiped out my 32/64-bit version 7/8 kernels in the process :P
Does anyone know how to programmatically select all cells of a given type? There's NotebookFind to find content, there's NotebookLocate to find tags, but what about finding e.g. all Code cells?
@OleksandrR is there an easy way to reset them or some of them to default (other than say deleting init.m)? I found out just today that they're persistent and all the little annoyances I had been having all this while were due to stuff I was messing with (incorrectly!) while trying to answer questions
I've created a notebook for use in an in-class presentation. There is a fair amount of MMA code, and my students know nothing about MMA nor do they need to. I don't want to distract them with the code. I understand how to collapse the input cells and show only the output, but the input cells expa...
@OleksandrR yeah, same here... I'm still learning to interact with the kernel and frontend separately like szabolcs does.. it has always been just the notebook for me
@yoda I guess you can delete init.m once, then DumpSave["FEDefaults.mx",Options[$FrontEnd]] and reload it if you mess something up. Other than that just remember to set options on $FrontEndSession rather than $FrontEnd.
@halirutan What do you think about including the FrontEnd` context in the highlighter too? Most of these symbols are actually documented, but work slightly different from the System` context equivalents (in that they can be sent to the FE directly for execution)
Is it possible to have several highlighting scripts working together? I'd be a bit reluctant to put too many symbols into the standard highlighter as it's a strain on the JavaScript interpreter/regex engine but if you need to highlight other symbols occasionally perhaps an additional highlighter can be added? (BTW @halirutan, fantastic job on the current highlighting. It gets everything (syntactically) right as far as I can see.)
At startup it's set to {DockedCells -> FEPrivate`FrontEndResource["FEExpressions", "HomeEditionBar"]}, but setting it to {} only lasts as long as the session
@Heike I deliberatelty asked you to set the option on $FrontEndSession in order not to break anything permanently ... did you try setting it on $FrontEnd ?
@Heike There is a resource for the HomeEditionBar. I assume that you can replace that with another. Not sure whether we should be advocating this here...
@OleksandrR Thanks, but it was very often @Szabolcs who did the testing and found the bugs. To answer your question: When the script sees a CODE tag, it transfers it to the prettify-script with our language extension. After this run, this is no longer CODE-text, it is broken into many styles. A second run with another script is not possible.
@Heike I didn't mean Kernel/init.m (yes, it's set after that), but FrontEnd/init.m, which is managed by the front end and contains lots of settings by default. Just clarifying in case you misunderstood.
In case anyone wants to see what that bar looks like, just evaluate SetOptions[$FrontEndSession, DockedCells -> FEPrivateFrontEndResource["FEExpressions", "HomeEditionBar"]]`
@OleksandrR what would work in this testing phase is to make your own version by simply adding or removing keywords. This is a task of only a few minutes. Download the script, the Mathematica-Code to create the keywords is in the comments. Adjust it like you want and replace the output in the keywords variable.
@Heike If nothing else works, you can search the Mathematica installation directory for the string "HomeEditionBar" (there must be some graphical grep-like utility in OS X I guess), find out what differs from the standard version, and change it
Does someone know whether our search on M.SE is powerful enough to find "FrontEnd`"? It should take capital letters into account and find the backtick.
@halirutan I don't think we can use search to find it, but it's not very common. It's typically come up in FrontEndExecute, so we can search for that as well
I think I'll just write a palette to set DockedCells->{} after start up. I don't really want to fiddle with the original files in $InstallationDirectory. It's just annoying that this banner is forced upon me.
@halirutan most of these posts contain that context, but actually it doesn't bother me at all if they are not highlighted. It's up to you, judge based on the current volume of keywords. :-) It was just an idea, not a request, and I'm worried about the script not getting accepted into prettify (because it's too long) ...
@Heike One last idea, but I am worried it might break something. I can't test for you though ... SetOptions[$FrontEnd, NotebookDynamicExpression :> (*hide docked cell*)]
@Szabolcs I have thought about this. For me is important, that we can use our full keywords-list here. I wouldn't mind to make a reduced version for the prettify-distribution. Will the SE-people include our extra-version or will they only include what's in the official prettify-distribution?
I have the following code:

instruments = FinancialData["^DJI", "Members"]

Dynamic[ticker]
ticker =.

@Heike I was just editing the FinancialData question, went in and out the edit box and then discovered Andy had been busy. No message as far as I can recall
@SjoerdCdeVries The same thing happened to me. I got a message that my version wasn't sufficiently different from Andy's version when I tried to commit the changes I made.
It would be nice if a post got locked while being edited.
Hi. I have a quick question. If I evaluate Table[AbsoluteTiming[myFunction[i,i]][[1]],{i,100}], will the table generated consist of 100 entries, or 100*100?
Because the evaluation seems to be extremely slow...
@CHM this is pretty common in Mathematica. Explicit loops are almost never the most efficient way to do things. The exception is if you are doing some funky compiling-to-C thing.
The values for "FontNWidth" of the first three fonts seem very similar on my system at least, but there is a good chance that they will be different on a different OS.
Well, Times is a skinny font, but its reported "FontNWidth" is larger than some of the others. Thus all the whitespace in the box when Times is chosen in the little Manipulate. So I suspect that the NWidth is more about the font size than anything else. But it is really cool. I can imagine some neat layout applications with interactive resizing to make room for the font chosen.
For this reason I'm surprised your answer hasn't yet attracted many upvotes.
Would you mind if I added the Manipulate above to your answer? I think it will make the point quite nicely.
@Szabolcs, Mike Samuel wrote me (I think it's ok to quote): "Sorry I've been slow. I am planning on reviewing the mathematica code, but have been slammed with other work. I should have some useful comments for you early this week."
So he did not forget us, which is very kind and since we are not in a hurry until we are out of the beta, I told him, he can take his time.
Say I have a function $f(x)$ that is given explicitly in its functional form, and I want to find its Fourier transform[1]. If $f$ is too complicated to have an analytic expression for $\hat f(k)$, how do I obtain it numerically?
The naive and stupid way, which I currently use, is evaluating the ...
