Adding points and their relative legend with tikz












1















The following code



begin{tikzpicture}[scale=0.7]

begin{axis}[xlabel={$s$},ylabel={$c$},legend pos=south east]

addlegendimage{empty legend}

addlegendentry{}

addplot+[smooth,draw=black,mark=oplus] coordinates

{(0.3,0.275)};

addlegendentry{$zeta=10$}

addplot+[smooth,draw=black,mark=oplus] coordinates

{(0.2,0.15)};

addlegendentry{$zeta=10$}

addplot+[smooth,draw=black,mark=x] coordinates

{(0.345743, 0.332178)};

addlegendentry{$zeta=15$}

addplot+[smooth,draw=black,mark=x] coordinates

{(0.154257, 0.0928216)};

addlegendentry{$zeta=15$}

end{axis}

end{tikzpicture}


produces the picture below:



enter image description here



In the legend I'd like only one description for different kinds of point. For example, we have that the cases 10 and 15 are repeated two times. The correct picture should be that:



enter image description here



EDIT



However, the code:



begin{tikzpicture}[scale=0.7]

begin{axis}[xlabel={$s$},ylabel={$c$},legend pos=south east]

addlegendimage{empty legend}

addlegendentry{}

addplot+[smooth,draw=black,mark=oplus] coordinates

{(0.3,0.275)};

addplot+[smooth,draw=black,mark=oplus] coordinates

{(0.2,0.15)};

addlegendentry{$zeta=10$}

addplot+[smooth,draw=black,mark=x] coordinates

{(0.345743, 0.332178)};

addplot+[smooth,draw=black,mark=x] coordinates

{(0.154257, 0.0928216)};

addlegendentry{$zeta=15$}

addplot+[smooth,draw=black,mark=o] coordinates

{(0.361803,0.352254)};

addplot+[smooth,draw=black,mark=o] coordinates

{(0.138197, 0.0727458)};

addlegendentry{$zeta=20$}

addplot+[smooth,draw=black,mark=square] coordinates

{(0.370416, 0.36302)};

addplot+[smooth,draw=black,mark=square] coordinates

{(0.129584, 0.0619801)};

addlegendentry{$zeta=25$}

end{axis}

end{tikzpicture}


does not solve my problem:

  • How about invoking the respective addlegendentry only once instead of twice?

One should never forget about the option forget plot, which allows you to disregard a plot for a legend. I added this to every other plot to obtain



documentclass[border=3.14mm,tikz]{standalone}

usepackage{pgfplots}

pgfplotsset{compat=1.16}

addplot+[smooth,draw=black,mark=oplus] coordinates

{(0.3,0.275)};

addplot+[smooth,draw=black,mark=oplus,forget plot] coordinates

{(0.2,0.15)};

addlegendentry{$zeta=10$}

            Contact image not getting when fetch all contact list from iPhone by CNContact

            up vote 0 down vote favorite I know this question already asked but not getting solution. From this code I will get all the information from the contact but image not found when open vcf files on mac os, also not getting when share this file. I use this stackoverflow link here but It's not help full. var contacts = [CNContact]() let keys = [CNContactVCardSerialization.descriptorForRequiredKeys() ] as [Any] let request = CNContactFetchRequest(keysToFetch: keys as! [CNKeyDescriptor]) do { try self.contactStore.enumerateContacts(with: request) { (contact, stop) in // Array containing all unified contacts from everywhere contacts.append(contact) } } catch { print("unable to fetch contacts") } do { let data = try

            count number of partitions of a set with n elements into k subsets

            up vote 6 down vote favorite 1 This program is for count number of partitions of a set with n elements into k subsets I am confusing here return k*countP(n-1, k) + countP(n-1, k-1); can some one explain what is happening here? why we are multiplying with k? NOTE->I know this is not the best way to calculate number of partitions that would be DP // A C++ program to count number of partitions // of a set with n elements into k subsets #include<iostream> using namespace std; // Returns count of different partitions of n // elements in k subsets int countP(int n, int k) { // Base cases if (n == 0 || k == 0 || k > n) return 0; if (k == 1 || k == n) return 1; // S(n+1, k) = k*S(n, k) + S(n, k-1) return k*countP(n-1, k) + countP(n-1, k-1); } // Driver program int ma

            A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

            Image
            0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{
