How to draw line through group plots in pgfplots? This issue has been driving me crazy for the past 10-20h. I have a group plot (pgfplots) where I have 2 plots one under another. I'd like to draw a vertical line (e.g. a helpline at x=150e-6) that would go through all of them.  When drawing inside the axis or rather nextgroupplot environment I can use something like this: \draw[thin] (axis cs:150e-6,\pgfkeysvalueof{/pgfplots/ymin}) -- (axis cs:150e-6,\pgfkeysvalueof{/pgfplots/ymax}); but this allows me to draw only on one of the subplots. If I go outside the axis environment I am able to draw on the entire {tikzpicture}, but I can't use the axis reference.  \begin{figure*}[h] \centering \begin{tikzpicture}  \begin{groupplot}[       group style = {group size=1 by 2, x descriptions at=edge bottom, vertical sep=0.2cm},       ytick={0, 1.8},       ymin=0,       ymax=3,       xmin=0,       xmax=550e-6,       change x base=true,       x SI prefix=micro]  \nextgroupplot \addplot table [x index = {0}, y index = {1}, col sep=comma] {plots/plot1reduced.csv};  \nextgroupplot[x unit=s] \addplot table [x index = {0}, y index = {3}, col sep=comma] {plots/plot1reduced.csv};  \draw[thin] (axis cs:150e-6,\pgfkeysvalueof{/pgfplots/ymin}) -- (axis cs:150e-6,\pgfkeysvalueof{/pgfplots/ymax});  \end{groupplot} \end{tikzpicture} \caption{Case 1} \label{fig:case1plot} \end{figure*} Consider:  I need to do this. I need do this.  My English grammar knowledge tells me that &quot;need&quot; doesn't have the same status as the modal verbs &quot;may&quot;, &quot;can&quot;, &quot;should&quot; and what not. Hence the second usage where two verbs appear consecutively is incorrect. But yesterday, my native English speaking friends (Americans) told me that &quot;I need compute this.&quot; is a perfectly grammatical sentence, and one is simply omitting the &quot;to&quot;. How can this be? Is it a colloquial usage but grammatically incorrect, or is it grammatically correct? If it is grammatically correct, is it because &quot;need&quot; is a semi-modal verb? EDIT: in particular, is it okay to use &quot;need compute&quot; in a scientific paper? EDIT2: the exact phrase that raised the question was &quot;The advantage of this representation is that we need only compute sums and products&quot; Are players allowed to pass a penalty kick? I saw a video of Johann Cruyff , isn't that against the rules? What is the proof that a force applied on a rigid body will cause it to rotate around its center of mass? tags of mundanity that are gratuitously applied to posts It's an additional unnecessary burden to the honest stacker during suggested edit duty. A question presents some code then the minor editor adds a tag like 'for-loop' or 'forms'.  These tags are so general that they only have a handful of followers. They serve no useful purpose and are the cause of many too minor edits. Why not permit culling of generic tags? Having just  from any of the queues, it was reviewing close votes; however, this audit was flawed in that I didn't even cast a close vote.  Often I press the Close button to preview greater detail and sentiment of the closure, spawning the Why should this question be closed dialog box:    Especially for duplicates, where functionality is solely dependent on spawning this dialog.  From Closing > Duplicate, I can search or view selected duplicates:    Although, I realize general closure reasons are summarized on the page:    This question had 6-upvotes, but seemed very localized referencing subjective query is "taking too long" and even had a sqlfiddle link.  Maybe overly broad regarding performance tuning, the OP was posting like a forum with two answer posts to his own question  and  with one of those answers asking follow-up questions.    Wanting to gauge community response, current closure totals struck my curiosity.  So, I pressed the Close button and boom - oh, the humanity!  I failed, and didn't even cast a close vote.    Votes are not cast until a reason for closure is selected and Vote to Close is pressed.  Taking any review very seriously on this site, it only seems fair that my review quality is tested through actionable steps instead of clicking for more detailed information, leveraging the functional design of the close vote user interface.  Sure, it's complex to seed fake vote totals, and then there's controversy of mindless voting in the majority or people who simply cherry pick 4-vote questions.  Still though, it seems unfair I should hesitate to review further information of vote totals and duplicates before skipping due to the implementation of this audit. Why three-phase power? Why not a higher number of phases? Is there a reason, beyond historical reasons, that three phases has become the dominant number of phases?  I am aware of the advantages against one phase and two phase, namely the reduced amount of conductor needed, and that motors can provide torque when stalled (and less pulsation).  Is this solely due to diminishing returns, with only a small increase in smoothness of torque application, at the cost of increased complexity (increased number of wires (albeit of smaller CSA)).  To be clear, the phases are all evenly distributed, that is, five phases separated by 72 degrees. How to modify itemize vertical spacing within blocks in beamer? I have noticed that when I have "itemize" environments defined within blocks in beamer, that they introduce more vertical spacing between the top and the bottom of the blocks, than vertical text. Since I have a slide with some text filled blocks and directly after, a slide with only "itemize" holding blocks, I would like the spacing between the itemized text and the block to be the same as for regular text.   On  I have read about "squeeze" option, but it doesn't seem to work...   Additional info:  The problem is in the additional vertical space that is included by the "\itemize" environment. I have found  on how to remove vertical spacing from the itemize list, and I am using this approach. However, it is a brute force approach. What I would like to know if it is possible to have the same vertical space between the end of the itemize list and the bottom of a block, as the one set between the normal text and the bottom of the block.

Why are only certain shutter speeds or apertures available? For the exposure control function DSLRs there are specific shutter speeds available. For example there are 1/4, 1/100, 1/500. Why, even in high end DSLRs, is there no option to use a custom shutter speed (such as 1/19)?   If the camera can do 1/4000, why can't it do 1/33?  Similarly, why are the aperture choices limited?  Why is it a technical challenge to add extra shutter speeds or aperture settings? DES-X , computation load and storage How to reset main user account? My main account got messed up, as I tried to fix it things went downhills.   keyboard mess - tried unity --restore and deleting .gconf2*, fail deleted .* in ~, total havoc. Chromium and Firefox crashes etc.   Now, another user account is fully functioning, but I really want my regular username back.  Is there any way to completely wipe the settings for the messed up account or copy the profile from the functioning user? I'm having a problem finding out a way to project from top view and the side view so I texture better. It just replaces the current projection with the top view    So is it possible to project from view twice on the same image? The repository 'http://ppa.launchpad.net/mdeguzis/libregeek/ubuntu focal Release' does not have a Release file "named" vs "that is named" Formal Proof that area of a rectangle is $ab$ I tried to prove that the area of a rectangle is $ab$ given side lengths $a$ and $b$.  The best I can do is the assume the area of a $1\times1$ square is $1$. Then not the number of $1\times1$ squares that fit in an $a\times b$ rectangle is $ab$. Therefore area is $a\cdot b$. This does not seem rigorous however. Error java.lang.OutOfMemoryError: GC overhead limit exceeded Down vote changed to up vote caused reputation meter to pass daily maximum I just experienced a minor visual bug.  I had an answer that earned 2 down votes and 22+ upvotes, earning me the daily maximum of +200. Upon making some edits to the answer at the behest of the comments, one of the users who down voted changed their vote. Now my reputation meter shows that I gained +202 for the day.    This correctly did NOT affect my reputation, as I still only gained 200, so it is merely a minor display bug.  This appears in the achievements drop down and my reputation tab on my profile. I use bash on both my Mac and as my cygwin shell. Overall, I'm quite pleased with it.  My one complaint however is that its TAB completion isn't as good as Windows Command Line TAB completion.   For example, if there are two files with the same prefix, then bash just beeps at me when I try to TAB complete. If I keep nailing TAB, then it will eventually show me a list of potential files.  I definately prefer how Windows will cycle through potential files right on the command line.   Is there a way to get bash to operate similar to Windows Command Line in this regard?  If there isn't (I do not want to switch shells), am I missing something about TAB completion in bash? Is there a more efficient way to use it? What gifts would be welcome for a Swedish host family?
