Is there a way to get for all tikz-plots in one LaTeX document the same distance between the plot marks, ie the distance between the marks should be independent of sample size. It would be really great if this change wouldn’t interfere with the legend like change the position of the marker in the legend etc. Thanks.

Edit: Unfortunately the distance of all data points (not in the mini example but for the real data) is not the same therefore it would be nice if I could define distance between the marks in cm.

documentclass[tikz,border=1mm]{standalone}
usepackage{pgfplots}
usetikzlibrary{decorations.markings}
pgfplotsset{compat=1.11}
%tikzset{mark/.style={
%        decoration={
%            markings,
%            mark= between positions 0 and 1 step 5mm with
%                {
%                %node[circle,inner sep=2pt,fill=blue]{};
%            },
%        },
%        postaction={decorate}
%    }
%}
begin{document}
begin{tikzpicture}
begin{axis}[]
addplot[
  blue,
  domain=0:3,
  samples=100,
  mark=*
  ]
{exp(x)};
addlegendentry{exp(x)};

addplot[
  red,
  domain=0:3,
  samples=20,
  mark=diamond
  ]
{4*x};
addlegendentry{4x};

end{axis}
end{tikzpicture}
end{document}

edit: Is is possible to pass to tikz such options like mark size or mark options={solid} ?

    addplot [color=black,loosely dotted,line width=1.5pt, mark=*,mark size=3pt, mark=diamond,mark options={solid}]

edit2: I found out how I can set the marks solid in the legend but how can I do the same in for the plot? Any ideas how to get the plot marks solid in the actual plot?

tikzset{
  nomorepostactions/.code={lettikz@postactions=pgfutil@empty},
  mymark/.style={decoration={markings,
    mark= between positions 0 and 1 step (1/11)*pgfdecoratedpathlength with{%
        pgfuseplotmark{#1},%
      },  
    },
    postaction={decorate},
    /pgfplots/legend image post style={mark=#1,every path/.append style={nomorepostactions}},
  },
  every mark/.append style={solid,mark size=3},
}

I am drawing a tree with tikz, namely, using tikz-qtree-compat for simpler syntax.
On the tree there can be nodes of different height but then branches become messy.
I want to add an instruction where distance between the south point of a mother nodes and the north point of a child node is constant.

MWE: https://www.overleaf.com/2453721thvhsh#/6394537/

documentclass[10pt]{report}

usepackage{tikz-qtree-compat}  % draw trees with simple syntax

begin{document}

wanted but obtained non-general way:
begin{tikzpicture}[baseline=-20pt, grow=down]
tikzset{level distance = 25pt, sibling distance = 30pt}
tikzset{every tree node/.style={align=center,anchor=north}}
tikzset{level 1/.style={level distance=38pt}}  
tikzset{level 2/.style={level distance=60pt}}  
tikzset{level 4/.style={level distance=60pt}}  
Tree
[.node{A\A};
 [.node{B\B\B\B};

  [.node{D\D\D};
   [.node at(0,-25pt){F\F};
    [.node{G};]
   ]
  ]

end{tikzpicture}

without any modification looks like:

tikzset{level distance = 25pt, sibling distance = 30pt}
tikzset{every tree node/.style={align=center,anchor=north}}
%tikzet{some single instruction that fix all trees in this way}

Can someone help me? I am trying to apply the following diagram in latex, and have tried to work with existing examples. The bubble map is one I created in Bubl.us. The problem is that I’m trying to fit it on one page, and I’m having problems with it. I’d like to clean it up using UML chart instead of the tree look. Any help is appreciated. I am listing the .cls file and my template for help. Thanks very much.

I would like to know how can I choose a column from a multiple data file, and how can I operate with them.

I mean in gnuplot I used this code to plot the second column depending on the first and also take the minus one time the second.

plot “file.dat” u 1:($2*(-1))

So could someone help me which is the equivalent of using in tikz?
Thank you!

I am hoping to recreate the image you see below in tex (the original here was done in Word). After snooping around for some time, I see that this should be done using the Tikz package. However, I don’t have any experience with this package and am trying to prepare this for a lecture relatively soon (poor planning on my part). Can anyone help recreate this image?

Thank you! Any and all help is much appreciated!

I have attached a minimum working example above and it provides the following picture.

The following are some challenges I face:

1. Add the three lines from the inputs iabc, and vabc,
2. In the abc/dq block, I want to draw the diagonal line and write abc on one side and dq on the other side.

Any modification or necessary update to the code is appreciated.

I’m wondering whether is possible to draw a Moebius Strip using TikZ. The closest thing I’ve seen is in Texamples’ page, but no luck so far!

Do you have any ideas? I don’t even have a MWE (sorry)

I’d like to draw this very simple diagram below. No need those rounded corners on the feedback line.

I tried to follow other guides, but I don’t know how to draw the feedback line nor how to distribute the inputs vertically on the left side of the rectangle.

Below is my try:

documentclass{article}

usepackage{tikz}
usetikzlibrary{shapes,arrows,positioning}
begin{document}

tikzstyle{block} = [draw, rectangle, minimum height=3em, minimum width=3em]
tikzstyle{virtual} = [coordinate]

begin{tikzpicture}[auto, node distance=2cm]
    % Place nodes
    node [virtual]                 (input)     {};
    node [block, right of=input]   (model)     {Model};
    node [virtual, right of=model] (output)    {};
    node [virtual, below of=model] (feedback)  {};
    % Connect nodes
    draw [->] (input) -- node {$u$} (model);
    draw [->] (model) -- node [name=y] {$y$}(output);
    draw [->] (y) |- (feedback);
end{tikzpicture}

end{document}

Rendering as follows:

Could you please guide me here? Thanks

Using TikZ, the shade option is very convenient to produce color shadings, but it produces only linear color gradients. Is it possible to obtain other transitions, and especially a logarithmic one?

Thanks!

Edit:

Here is an example for the linear case:

documentclass[border=5mm]{standalone}
usepackage{tikz}
begin{document}

begin{tikzpicture}
shade[left color=black, right color=white] (0,0) rectangle (10,1);
end{tikzpicture}

end{document}

For my poster I am using the tikzfigure environment within tikzposter to add figures. It works fine, but I want to have the figure captions justified or left aligned instead of centered.

I have tried justify or begin{flushleft} ... end{flushleft} within the caption, changing the tikzposter class file but it does not work.

Thanks!

I’m trying to put together a pgfplot inside a pre-existing tikz picture. But somehow the axis I create with pfgplot has different units and I’m not sure how to make the two things fit.

The code is:

documentclass[11pt]{amsart}

draw [line width=0.05cm] (0,3) to [out=25,in=150] (1.5,3.5) to [out=-30,in=120] (3,3) to [out=-50,in=-155] (4,3);

begin{axis}[samples=3000]
addplot[very thick,red ]plot (x, {x*sin(1/abs(x))});
end{axis}

end{document}  

I would like somehow for the graph of the function x sin(1/|x|) (properly scaled and shifted) to connect the between the two pre-existing red lines smoothly.

Any help would be greatly appreciated.

** EDIT **

Here is some improved code:

  draw [line width=0.05cm] (0,1) to [out=80,in=180] (1,1) to [out=0,in=180] (2.5,1.5) to [out=0,in=-100] (4,1);

  path [fill=lightgray] (0,3) to [out=25,in=150] (1.5,3.5) to [out=-30,in=120] (3,3) to [out=-50,in=-155] (4,3) to (4,4.3) to (0,4.3);     draw [line width=0.05cm] (0,3) to [out=25,in=150] (1.5,3.5) to [out=-30,in=120] (3,3) to [out=-50,in=-155] (4,3);                   draw [thin, ->] (-0.1,0) -- (4.5,0);

  draw [thin, ->] (0, -0.1) -- (0, 4.5);

      draw [thin] (4, -0.1) -- (4, 0.1);

      node [below] at (4, -0.1) {$2pi$};

       node [below] at (0, -0.1) {$0$};

        draw [dashed] (-0.1, 2) -- (4,2);

draw [line width=0.05cm, red] (1, 1) to [out=0, in=180] (1.5,1.5);
draw [line width=0.05cm, red] (2.5,2.5) to [out=0, in=180] (3, 3);
begin{axis}[samples=9000,scale only axis,axis lines=none]
addplot[very thick,red ]plot (x, {0.1*(x + 3)*sin((1/abs((x + 3)))r)});
end{axis}

I’m trying to make use of the newer (pgf > 3.0) graphdrawing layouts to do class diagrams, but I can’t seem to figure out how to get arrows to attach to the outline of a rectangle split. I’ve read about the anchor points for a rectangle split in the documentation at https://www.ctan.org/pkg/pgf, but I can’t figure out how to make use of them.

Basically, in the example below the arrows should attach at the outside of the rectangle split. I have no idea why they are attaching instead to the middle “two” box. Any ideas?

documentclass{standalone}
usepackage{tikz}
usetikzlibrary{graphs,graphdrawing,arrows,shapes.multipart}
usegdlibrary{layered}
begin{document}

tikzset{object/.style={draw, rectangle split, rectangle split parts=3,
    rounded corners, rectangle split part align={center,left,left}},

def methods {nodepart{three}}

begin{tikzpicture} [layered layout, >=latex]

};

end{tikzpicture}
end{document}

Expectations

I would like to make my own periodic table in LaTeX. It should (…)

• have a space between the orbital groups (s, p, d, f)
• every group should have rounded corners
• the different “categories” (earth alkali metal and so on) should be colored

Each element should have this information

• Atomic Weight
• Atomic Number
• Chemical Symbol
• Chemical Name
• Count of electrons in the orbitals

Here an image how I thought it should look like

And here an image what I meant with electron counts in orbitals

Source Code
I have tried something myself. I thought I could “borrow” some of the code from here. Some of the information in the link is wrong. So I thought of making a new code using a list of all need information. Sirius3 helped me in a German Python Forum:

Problems

• Arranging all elements (all 118 elements are behind each other)
• Make round corners for each group of orbitals
• Give every group a color (Alkali Metal, Alkali Earth Metal …)
• Writing the electron count from the Aufbau principle for each element
• Writing the number of period/groups for each period/group

I know it is much, but it would be nice if you could help me a little further … I am just stuck :/

Thank you very much in advance! Kind regards!

I’ve 4 data sets that I’d like to present as a stack using pgfplots‘ groupplot library. What I’m struggling with is that the first data set has a larger horizontal range to the remaining three. I’d like to minimize the range of each data set so as to most clearly show my data, meaning that using the larger range of the first data set for all the plots is not acceptable to me.

My question is: how can I display the relevant x tick labels under the first graph and last, but not under the second and third? MWE below.

I came across the PSTricks animation located at

http://melusine.eu.org/syracuse/pstricks/pst-solides3d/animations/a43/
http://i.stack.imgur.com/NlqHZ.gif

and noticed that it uses a light object / source for the color / shading of the object. This can be seen from the code as found at

http://melusine.eu.org/syracuse/pstricks/pst-solides3d/animations/a43/anim.tex

I make all of my pictures with PGF and would like to use light sources in a similar manner as done in the PSTricks animation above. Unfortunately, this has is not implemented (yet) in PGF.

Is it perhaps possible to do some post processing of my PGF pictures to get the effect of a light source? I am thinking of PSTricks, Asymptote and Adobe Illustrator, but I can’t seem to manage.

I think it would be great if we could produce vector graphics pictures with light sources in PGF like for instance

I would like to label the length of four line segments in a certain plot. In the plot, the length of line segment PQ should be labeled a, the length of line segment QS should be labeled b, the length of line segment PR should be labeled “c, and the length of line segment RT should be labeled d.

The label for a can be placed in the middle of a line segment parallel to and just below line k (containing points P, Q, and R). I saw on this web site that the command draw[|<->|] is used for this display. The label for a can also be placed below a { that is drawn below the line segment PQ. I did not see in the TikZ manual how to do this.

Also, I would like the line segment or { that is used to indicate the lengths of line segment PQ and PR to be placed on top of the plot – so that there is some white space about it. The axes and lines ell_{1} and ell_{2} would interfere without placing the line segment or { on top.
