plotting - How to avoid font substitution with Mathematica fonts?

When I export a Plot to PDF, a journal publisher complains that they do not have the Mathematica fonts. I believe there is a way to inhibit Mathematica from substituting its fonts (e.g., for "(") but I cannot figure it out. I tried this but it did not work.

 Plot[ , BaseStyle -> {PrivateFontOptions -> {"OperatorSubstitution" ->False}}]

Answer

The "OperatorSubstitution" option does prevent the use of Mathematica fonts, but only for those cases where there were ASCII equivalents. So if your graphic contains expressions which use, for example, parentheses, brackets, braces, or various ASCII operators (plus, minus, asterisk, etc.), then the "OperatorSubstitution" is exactly what you want and you are using it correctly.

What the option does not prevent, however, is the use of Mathematica fonts where there are no ASCII equivalents. For example, if your graphic contains a Greek letter, it will use Mathematica1. If it contains an unusual relational operator, it'll probably use Mathematica3.

However, it should be the case that, by default, Mathematica will embed the numbered Mathematica fonts that it relies on in any given graphic when doing a PDF export. If this isn't happening for you or if this isn't acceptable to your publisher, perhaps we might discuss it further in the comments.

functions - Get leading series expansion term?

Given a function f[x] , I would like to have a function leadingSeries that returns just the leading term in the series around x=0 . For example: leadingSeries[(1/x + 2)/(4 + 1/x^2 + x)] x and leadingSeries[(1/x + 2 + (1 - 1/x^3)/4)/(4 + x)] -(1/(16 x^3)) Is there such a function in Mathematica? Or maybe one can implement it efficiently? EDIT I finally went with the following implementation, based on Carl Woll 's answer: lds[ex_,x_]:=( (ex/.x->(x+O[x]^2))/.SeriesData[U_,Z_,L_List,Mi_,Ma_,De_]:>SeriesData[U,Z,{L[[1]]},Mi,Mi+1,De]//Quiet//Normal) The advantage is, that this one also properly works with functions whose leading term is a constant: lds[Exp[x],x] 1 Answer Update 1 Updated to eliminate SeriesData and to not return additional terms Perhaps you could use: leadingSeries[expr_, x_] := Normal[expr /. x->(x+O[x]^2) /. a_List :> Take[a, 1]] Then for your examples: leadingSeries[(1/x + 2)/(4 + 1/x^2 + x), x] leadingSeries[Exp[x], x] leadingSeries[(1/x + 2 + (1 - 1/x...

front end - keyboard shortcut to invoke Insert new matrix

I frequently need to type in some matrices, and the menu command Insert > Table/Matrix > New... allows matrices with lines drawn between columns and rows, which is very helpful. I would like to make a keyboard shortcut for it, but cannot find the relevant frontend token command (4209405) for it. Since the FullForm[] and InputForm[] of matrices with lines drawn between rows and columns is the same as those without lines, it's hard to do this via 3rd party system-wide text expanders (e.g. autohotkey or atext on mac). How does one assign a keyboard shortcut for the menu item Insert > Table/Matrix > New... , preferably using only mathematica? Thanks! Answer In the MenuSetup.tr (for linux located in the $InstallationDirectory/SystemFiles/FrontEnd/TextResources/X/ directory), I changed the line MenuItem["&New...", "CreateGridBoxDialog"] to read MenuItem["&New...", "CreateGridBoxDialog", MenuKey["m", Modifiers-...
