I'm trying to fill the area between the two $z$-scores but I'm not having any luck. Could someone please help me with this?  \begin{tikzpicture} \begin{axis}[   no markers,    domain=0:6,    samples=100,   ymin=0,   axis lines*=left,    every axis y label/.style={at=(current axis.above origin),anchor=south},   every axis x label/.style={at=(current axis.right of origin),anchor=west},   height=5cm,    width=12cm,   xtick=\empty,    ytick=\empty,   enlargelimits=false,    clip=false,    axis on top,   grid = major,   hide y axis   ]  \addplot [very thick,cyan!50!black] {gauss(x, 3, 1)};  \pgfmathsetmacro\valueB{gauss(1,1,7)} \pgfmathsetmacro\valueA{gauss(1,1,1.7)} \pgfmathsetmacro\valueC{gauss(1,1,1)}  \draw [very thick, red]  (axis cs:1,0) -- (axis cs:1,\valueB); \draw [very thick, red]  (axis cs:2,0) -- (axis cs:2,\valueA); \draw [very thick, red]  (axis cs:3,0) -- (axis cs:3,\valueC);  \node[below] at (axis cs:3, 0)  {$\mu$};  \node[below] at (axis cs: 2, 0) {$z=-1.8$}; \node[below] at (axis cs: 1,0) {$z=-2.97$}; \end{axis} \end{tikzpicture}
I want to hatch the area under a curve (graph of a function) with oblique lines on an interval (to illustrate the function's integral on that interval). This can be done elegantly in gnuplot...   ...but I simply cannot reproduce this with pgfplots. The only solution I managed to find with google is the use of the patterns tikz library, however it is unacceptibly ugly:    I'm not aware of any way to alter the color, line width and - especially - the distance between the hatching lines when patterns library is employed. Is there any way to set it? (So that I can change it to resemble the gnuplot version.)  Or, should I choose a completely different approach to reproduce the gnuplot-style hatching...?  Also note that   pgfplots changes the color of the x-axis to red on the interval (which is not a critical problem, of course, but not elegant). the legend for the filling is much more logical in case of gnuplot. Can I reproduce it with pgfplots?   Here is the code I currently use:  \begin{figure}[ht!] \centering \begin{tikzpicture}     \begin{axis}[xmin=-4,xmax=4,xlabel={z},ymin=0,ymax=1]      \addplot[color=red,domain=-4:4,samples=100] {1/sqrt(2*pi)*exp(-x^2/2)};     \addlegendentry{z}     \addplot[color=red,fill=red, pattern=north east lines,  domain=0:1,samples=100] {1/sqrt(2*pi)*exp(-x^2/2)} \closedcycle;     \addlegendentry{Interval}     \end{axis} \end{tikzpicture} \end{figure}
How to use IDM on Mozilla Firefox Quantum I want to use Internet Download Manager for downloading on Firefox. According to this  it can be done with the extension called Flashgot. But Flashgot does not work on new Firefox Quantum. However, I found  that can be used to interrupt browser's downloading jobs by redirecting these jobs to an external download manager like Internet Download Manager (IDM). But I don't know how to integrate IDM with this new extension. I wrote IDM's location (/.wine/drive_c/Program Files (x86)/Internet Download Manager/IDMan.exe) in the box that says "Path to the executable" but when I try to download something, an error is appearing.

(initramfs) _   How can I fix this? What's up with the operating voltages 5 V, 3.3 V, 2.5 V, 1.8 V, etc.? I'm studying abstract algebra for the first time.  let $F$ be a field. I learned that polynomials over field $F$ means polynomials with coefficients in $F$ (denoted by $F[x]$). But when I keep studying, I get to confused the word, 'polynomial functions from $F$ to $F$'.  Firstly, I consider this as induced functions from $F[x]$, so I guess all coefficients of these functions are in $F$. But let $F_{4}$ be a finite field consisting of four elements $\{0, 1, a, b\}$. and let $f: \{0,1\} \rightarrow \{0,1\}$ be a function defined by $$ f(x)=ax^2-ax$$ Since $\{0,1\}$ is a subfield of $F_{4}$ and $f(0)=0, f(1)=0$, I think $f$ is a example polynomial functions from $F$ to $F$ of which coefficients are not in $F$. Am I wrong? if so, please help me.  I encounter this problem while solving 'the set of all polynomial functions from $\Bbb{Z_{3}}$ to $\Bbb{Z_{3}}$ cannot possibly be isomorphic to $\Bbb{Z_{3}}[x]$'. Classical car collision I have a very confusing discussion with a friend of mine.  2 cars ($car_a$ and $car_b$) of the same mass $m$ are on a collision course. Both cars travel at $50_\frac{km}{h}$ towards each other.  They collide. Ignoring any shreds and collateral damage, what is the speed of collision that the driver of $car_a$ felt?  What I mean is, if $car_a$ were to be driven into an infinite mass wall, what would the velocity be to replicate the damage caused by the initial collision? Is there a way to insert Keyboard Glyphs in Google Docs? Here on the StackExchange framework we have a nice feature, which is apparently called "Keyboard Glyphs" (cf. ):     CTRL+Z   Is there a way (e.g. with an Add-On) to do the same in Google Docs? I browsed the Add-Ons but did not find anything, maybe it's hidden somewhere different (e.g. in a Code Formatting Plugin). Recently, my answers are showing at the bottom of the page, even though I got good scores on those answers.       How do I change this back? Is it possible to know who voted my question/answer up or down? If not, then is it possible to include this feature? By this feature we can come to know if you are being voted up by question owner or persons giving other answers to same question or just the visitors of that question thread.  Like...  If it is a group of people giving other answers, then your answer is most correct If it is readers of that question, then your answer is more popular SQL to find the number of distinct values in a column I can select all the distinct values in a column in the following ways:   SELECT DISTINCT column_name FROM table_name; SELECT column_name FROM table_name GROUP BY column_name;   But how do I get the row count from that query? Is a subquery required? I'm adding a title clock in the foot line of a beamer slide, if I compile it with pdfLaTeX it works fine; while the clock doesn't align in the middle vertically if compiling with XeLaTeX.

Is there an English word meaning "the use of uncommon words" or similar? Why is there a discrepancy in disk usage reported by df and du? I have a Linux CentOS server, the OS+packages used around 5GB. Then, I transferred 97GB data from a Windows server to two folders on this Linux server, after calculated the disk usage, I see the total size of the two folders is larger than the disk used size.  Run du -sh on each folder, one use 50GB, the other one use 47GB  But run df -h, the used space is 96GB. (50GB + 47GB + 5GB) > 96GB  Is there any problem? Those two folders contain lots of files (1 million+). Thanks. JTable won't show column headers How to create csv files in controller method from list Can misused Schema.org hurt SEO? I've inherited a site where I noticed that    there is an excessive use of Schema.org in all navigation elements pages describing products are marked as itemtype="http://schema.org/CreativeWork"   So I'm wondering if these tags are sending the wrong message and not truly optimized. I realize that the nav (1) is done in some themes, but I'm more worried about (2). Can it be a hit SEO-wise to mislabel pages instead of products?

How do I check that multiple keys are in a dict in a single pass? I'd like to have Ubuntu installed on a USB stick, that I could plug in (almost) any computer and boot from it, and that I could use (almost) normally, as if it was installed on that computer. I'd also like to have a data partition on it that could be used by (almost) any computer, mostly to store some portable apps, just in case.    I've been told that if I installed Ubuntu in BIOS mode, I wouldn't be able to boot from a computer in UEFI mode, and vice versa.  Since I'd like to be able to boot on any computer, it's a big problem.  What can I do to be able to boot on computers in BIOS or UEFI modes in my case?  I've been searching for solutions but most of them are for specific needs that are different than mine, so it's difficult to extract the minimum requirements from those solutions to apply them to my problem.  Is there a simple, "clean" and quite generic solution to this problem?  I'd appreciate some explainations about the reasons why a specific solution is good or a specific step is needed.
