In the following plot, I am getting a warning. I know it has to do something with the coordinates but can't solve it for sure. If anyone can guide me in the right direction, it would be really helpful.
Package pgf Warning: No path specified that can be filled on input

These warnings arise because you are not only filling this path, you are also drawing the markers and the label markers in the same step.
If you decompose this into two separate steps, you can avoid the warnings:

How can I get the bounding box coordinates for the pgfplot below? I need the coordiates in pgfplot space. (current axis.south west) and (current bounding box.south west), for example, do not give what I need. I'm expecting something like SW = (-7,-1.1), NE = (8.2,1.4), which would extend to the right beyond the red rectangle.

How to draw this graph in LaTeX? I have used TikZ but I can't get it done exactly.
This is what I have tried so far:
\begin{tikzpicture}
\tkzInit[xmax=6,ymax=6,xmin=-6,ymin=-1]
\tkzAxeXY
\draw[thick] (6,3) -- (-4,5);
\filldraw[black] (6,3) circle (2pt) node[anchor=west] {A(6,3)};
\filldraw[black] (-4,5) circle (2pt) node[anchor=east] {B(-4,5)};
\end{tikzpicture}
Using regular pgfplots you could do the following: Draw the line with the points you choose and label them with nodes. Then draw the additional distance markers using \draw in the axis coordinate system (The concrete positions of all elements may have to be adjusted).
\documentclass{article}
\usepackage{tikz}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
\tiny
\begin{axis}[
width = 6cm,
height = 4cm,
ymajorgrids = true,
ymin=-1,
ymax=7,
xmin=-6,
xmax=6,
xtick distance=1,
ytick distance=1,
axis y line*=center,
axis x line*=center,
enlarge x limits=.12
]
\addplot+[sharp plot] coordinates {(6,3) (1,4) (-4,5) } node[below=1mm, pos=0] {A(6,3)}
node[pos=0.45,below=1mm] {P(x,y)}
node[pos=1,below=1mm] {B(-4,5)};
\draw[|-|] (axis cs:1.2,5) -- node [above, rotate=-10] {m=13} (axis cs:6.3,3.9);
\draw[|-|] (axis cs:-3.8,6) -- node [above, rotate=-10, pos=.3] {n=2} (axis cs:1.2,5);
\end{axis}
\end{tikzpicture}
\end{document}
Output:
I have the following image:
and I want its elements to appear in a certain order in my beamer presentation. For the moment, I'm trying to make a_1, a_2 appear in a second slide. I'm using this code:
\documentclass{beamer}
\usepackage{textcomp}
\usepackage{tikz}
\usetheme{Madrid}
\begin{document}
\begin{frame}{}
\usetikzlibrary{shapes,arrows, positioning, calc}
\tikzset{%
block/.style = {rounded corners, draw, thick, circle, minimum height = 3em,
minimum width = 3em, fill = yellow!50},
point/.style = {coordinate}, % Input
}
\begin{tikzpicture}[auto, thick, node distance=2cm, >=triangle 45]
%\node[block] (A1) at (0,0) {$A_1$};
%\node[block, right = 1cm of A1] (A2) {$A_2$};
\node[below = of A1] (a1) {{\visible<2->{$a_1$}}};
\node[below = of A2] (a2) {{\visible<2->{$a_2$}}};
\node[below = of A1] (a1) {$a_1$};
\node[below = of A2] (a2) {$a_2$};
\draw[->] (A1.south) ++(0,-0.3) -- ++(0, -1.3);
\draw[->] (A2.south) ++(0,-0.3) -- ++(0, -1.3);
\end{tikzpicture}
\end{frame}
\end{document}
but all I get is this:
I get errors like: "unknown arrow tip kind 'triangle 45'" and also "unknown operator 'o' or 'of ' in (of A1).
It's my first time using Tikz, and I'm not really practical with beamer tools like \onslide, \only or \visible. I think I could create different images, one for each frame, and then add them with \includegraphics and \pause, but it would be more practical if I managed to achieve the same result without creating different pictures. Any help would be really appreciated.
load your tikz libraries in the preamble, not inside the frame
you can use the overlay-beamer-styles library to control the appearance of the nodes
\documentclass{beamer}
\usepackage{textcomp}
\usepackage{tikz}
\usetheme{Madrid}
\usetikzlibrary{shapes,arrows, positioning, calc}
\usetikzlibrary{overlay-beamer-styles}
\tikzset{%
block/.style = {rounded corners, draw, thick, circle, minimum height = 3em,
minimum width = 3em, fill = yellow!50},
point/.style = {coordinate}, % Input
}
\begin{document}
\begin{frame}{}
\begin{tikzpicture}[auto, thick, node distance=2cm, >=triangle 45]
\node[block] (A1) at (0,0) {$A_1$};
\node[block, right = 1cm of A1] (A2) {$A_2$};
\node[below = of A1, visible on=<2->] (a1) {$a_1$};
\node[below = of A2, visible on=<2->] (a2) {$a_2$};
\draw[->] (A1.south) ++(0,-0.3) -- ++(0, -1.3);
\draw[->] (A2.south) ++(0,-0.3) -- ++(0, -1.3);

I've got a problem with tikzpicture. I've made my cv in Latex but one thing isn't working fine. In a skill graph I got multiple entries. Here's the code.

I hope one of you could help me.

uncomment the
enlarge y limits={abs=1cm},
and it should work, or do you want to have different distances? Then try this code:
\documentclass[]{article}
\usepackage{tikz}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}[thick,every node/.style={font=\sffamily}]
\begin{axis}[ title=\textbf{Sprachen},
xbar,
width=12cm, height=3.5cm, enlarge y limits=0.5,
y axis line style = { opacity = 0 },
axis x line = none,
tickwidth = 0pt,
%xlabel={\#participants},
symbolic y coords={Französisch, Englisch, Deutsch},
ytick=data,
%nodes near coords,
nodes near coords align={horizontal}, ]
\addplot coordinates {(1,Deutsch) (0.65,Englisch) (0.3,Französisch)};
\end{axis}
\node[text width=3cm] at (1.5,-0.5)
{Grundkennt.};
\node[text width=3cm] at (5.25,-0.5)
{gut};
\node[text width=3cm] at (7.4,-0.5)
{sehr gut};
\draw (2.5,0.1) -- (2.5, 1.95);
\draw (5,0.1) -- (5, 1.95);
\end{tikzpicture}
\end{document}
I had to recode it and use an example from this page as template. I still don't know what caused this repeated language labels. But this solution should solve it and have decreased distances.
By the way, if you are looking for a good template for CV's in LaTeX look on Overleaf (I like moderncv).
