There are two relevant document class options:

* "fleqn" (flush left equation), which aligns the equation to the left. 
Used by itself, though, it leaves the equation number on the right.


* "leqno" (left equation number), which puts the equation number on the 
left. Used by itself, it centers the equation still.


BUT, if you use BOTH options, then you get what you want.

How to do it in LyX? Look at Document> Settings> Document Class. The 
"Custom" field allows you to enter class options. In your case, you 
could enter "fleqn,leqno". Any class options can be entered here.


However, LyX also has native support for this under Document> Settings> 
Math Options. The Formula Numbering Side option is self-explanatory. You 
would want "Left". This adds "leqno" behind the scenes. The other one is 
the Indent Formulas checkbox. The tooltip explains what it does: It 
indents instead of centering equations. So you can check that. If you 
leave it at "Default", then it just adds "fleqn"; you can also, however, 
control the indent here by selecting "Custom" and entering a length 
(which gets set as the \mathindent).


This is all in the Math manual, under Help.

To change the text color, just select the whole equation and Right
click → Text properties → Customize.

To change the background, you can either follow section 9 of the Math
editor manual you find under Help, or for a quick trick insert your
equation inside a "frame" (Insert → Frame) and play a bit with the frame
options.

Odd behavior of \protect in equation \tag

[Sanford Shieh]

I’m using lyx 2.631 and the tikzlings package, and put 
\protect\tikz\protect\panda in an equation \tag.  But after saving the .lyx 
file and reopening it the \protect vanishes.

Obviously more of an annoyance for having to retype the \protect than a serious 
bug, but is there a known solution?

Option for displaying equation labels less obstrusively?

[Klaus-Dieter Bauer]

Hello!

As it is currently implemented, equation labels are displayed as part of
the equation number in LyX's editor. Sadly, for longer, semantically
meaningful label names (e.g. "eq:maxwell-equations-in-vacuum"), this throws
off the formatting in the editor buffer: Instead of centering the equation,
the combination of label and equation is centered. A similar problem
occurs, when left-aligned equations with left-aligned numbering are used.

Is there some setting in LyX, that allows getting better alignment, without
sacrifizing the ability to use long label names?

latex equation copied from MathType generally shows redundant { }

[balabi]

Dear lyx developers and usersI am new to lyx. Before using lyx, I always use Mathtype software to typeset equations which can be downloaded from www.dessci.com/en/products/mathtype/ The equations in mathtype can be copied as latex format.for example, an _expression_ looks like thishttps://pasteboard.co/HpwLYea.pngis copied as latex code as below\left( {\begin{array}{*{20}{c}}{{e^{ - i\phi /2}}}\\{{e^{i\phi /2}}}\end{array}} \right)I then paste this latex code into lyx math mode, however, it shows like thishttps://pasteboard.co/HpwKWg4.pngwith annoying redundant { and } symbolHowever, if you tried any online latex equation editors likehttps://www.codecogs.comhttps://arachnoid.com/latex/etc.You will find the latex code copied from mathtype is perfect with any redundant { }So I think the latex equation interpretation in lyx should be improved. This issue should be solved. Thank you very much! looking forward to your reply.best regards

Attached.  I have two nonsense displayed equations.  The top is with
align, the bottom with eqnarray.  The extra spacing, as you call it,
justifies the two sides of the equation consistently with eqnarray.  I
think it's easier to read.

That is a good idea, and consistent with what JMarc suggested (of

I would prefer to have it go into the eqnarry environment rather than
AMS align, or at least default to three columns rather than 2, with the
= in the middle.  That way, following lines will have the = sign
aligned, which IMO is how it should be.

Well, you could prevent that by replacing "P(X<3)=2" with
"P\left(X<3\right)=2", which is easy to do in LyX.  It also looks
better.

But LyX doesn't understand them as delimiters unless they are written

I use this all the time. The slider would be useful as I often end up cutting 
and pasting. But I do not need the graphics; an easy way to insert the “&” at 
the right place would be great.

I can see how that would be useful, especially for when there are many
lines. I think it is too ambitious for what I'm planning on working on
(hopefully I can limit my edits to the function that does the

Indeed, I played with negative spaces previously but didn't get anything
useful.  I was hoping there might be a more elegant, e.g., preamble-only,
approach to redefine spacings for equations.  Regardless, I hadn't tried
inserting into the following item but rather before the restart of the
itemization.  If switching environments and negative spacing is the agreed
upon approach I'll see what I can cobble together into a module.

Thank you for your explanation and worked example (I really appreciate it
when people take the time to demonstrate a fix).  A minor complaint (and
why I didn't go this route originally), the vertical spacing before/after
the second equation is not consistent because of going between "standard"
and "itemize".  It's subtle, but is there a known fix?  I'm reluctant to
get into playing with hard-coded spacings in the preamble, but I'm willing
to if that's what it takes.

Once these types of items are hammered out, I'll create a submodule (and
will submit it to be considered for inclusion in future versions).

Thanks again (for this and your help to others that is very useful to learn
from).

Tim,

Whenever something like this happens I immediately wonder about whether
all the fonts are embedded in the PDF. If I check with Image Viewer
(I'm using Linux Mint), I get the reassuring message "All fonts are
either standard or embedded", with ten unexceptional Type 1 fonts, all
with Embedded subsets. And one Type 3 "No name" font described as
Embedded, not Embedded subset. The equations do render correctly with
this viewer, and with the Chrome viewer.

If I open the downloaded file with Acrobat Reader 9, it renders
correctly, but the Type 3 font is described as"

F56
Type: Type 3
Encoding: Custom
Actual Font: F56
Actual Font Type: Type 3

There is no mention of it being embedded.

I don't know where this font is coming from in your document, but it
may be the problem.

None of the viewers I tried had any problems with correctly displaying
your PDF.

I assume you are speaking about LyX-produced PDF output, right?

My guess is, that the user used a resolution/magnification so small, that
the thickness of the lines in = was rounded to 0 by the software.

There is no easy cure, some suggestions:

* whenever details are missing, magnify the document and see whether they
  turn up.
  
* use a font with bolder symbols (e.g. newtxmath)

* use a larger font size (Document>Settings>Fonts>Base Size)

Re: Bad equation renderings

[Joel Kulesza]

The equal sign shows up well for me in both Chrome and Safari.  I've had
good luck with Foxit on Windows; however, I suspect this is can be blamed
on it.

It might be interesting to force embedding the fonts in the PDF and see if
the user can see the equal signs then.

Hi Chen,

See the answer here. It is written in a general way so that you can
find out how to make shorcuts for many different LyX actions.

Re: how can i set up a shortcut for equation label?

[gadmm]

Dear Chen,

See in Preferences  Keyboard shortcuts. The action is label-insert and 
you can define a shortcut of your choice for it. In your case you will 
find label-copy-as-reference useful too, to later paste the reference.

Bad auto-splitting when switching to equation array

[Christoph Burschka]

In a math environment (display or environment), you can switch to an
EqnArray environment with Ctrl Enter or Shift Enter.

If there is already an equation, it will be automatically split into columns
on particular symbols, including = and a few other operators and arrows.

Unfortunately, it passes right over some symbols (such as \coloneqq or
\dblcolon). It also splits on the first symbol, so a = b \Leftrightarrow c
= d will become a=b\Leftrightarrow c=d rather than a=b 
\Leftrightarrow  c=d, but at least that can be avoided with parentheses.

Is there some way to add operators like \coloneqq and \dblcolon to the list
of symbols that equations will be split on?

resize equation output

[Neal Becker]

I have the misfortune to be commanded to produce ppt.  So I took one of my 
equations, in lyx.  I chose beamer so I get something that'll look good on a 
slide.  I put 
\beamertemplatenavigationsymbolsempty

so crop will work.

When exported export/pdf(crop), it looks OK, but it's too small.  I import to 
M$ 
PPT by opening in acroread and copy file to clipboard.

So I need something that'll resize the pdf (or convince lyx/beamer to output 
something bigger in the first place).

I tried the latter without success.

Putting in preamble
\geometry{paper=a4paper}

didn't seem help.

Finally, I found this magic incantation:

gs -sDEVICE=pdfwrite -sPAPERSIZE=a5 -dFIXEDMEDIA -dPDFFitPage -
dCompatibilityLevel=1.4 -o eq1_2.pdf eq1.pdf

Then run through
pdfcrop

Finally, not a bad result (oh, did you want that centered on the slide?)

Any better ideas?

Well, this does give you a space, but it doesn't conform to typesetting 
conventions,
because the text is treated as a bunch of variables. You can enter 
math-text mode by
hitting Ctrl-M, then type normally. The font choices are also availalbe

Inserting Space in Mathematical Equation

[Rich Shepard]

  I have an equation that contains words, such as '0.75 * Total Stream
Length'. I looked in Herbert's Typesetting Mathematics with LaTeX and
found a single index reference to 'space' that referred to something
different. Ctrl-space does nothing.

  How do I insert a space within an equation?

gives various spaces.  Ctrl-Shift-Space should also give you a medium space.


But, while you are in math-mode, you can enter a text box by clicking on 
the insert math icon again.  You see a blue-outlined rectangle, and 
what you type in that is regular, upright, text.  Including spaces.  So 
you can get Total Stream Length by just typing that, in this text box 
inside of math-mode.

It is probable that television drama of high caliber and produced by
first-rate artists will materially raise the level of dramatic taste
in the nation.

Inserting Space in Mathematical Equation

[Rich Shepard]

  I have an equation that contains words, such as '0.75 * Total Stream
Length'. I looked in Herbert's Typesetting Mathematics with LaTeX and
found a single index reference to 'space' that referred to something
different. Ctrl-space does nothing.

  How do I insert a space within an equation?
