[Tex/LaTex] different colors in xlabel (tikz latex pgfplot)

colorlabelsplottikz-pgf

I would like to change the color of a part of my x label in my pgf plot.

\begin{figure}[h!]
\begin{tikzpicture}
\begin{axis}[xtick pos=left,legend pos=south east, xlabel style={yshift=-0.5cm}, xlabel ={Anzahl \& Name},ylabel = {Treffer}, xmin=0, xmax=24 , xtick={1,..., 23}, width=16cm, height = 7cm, extra x ticks ={1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23}, extra x tick labels={24,20,29,7,21,9,23,6,17,14,28,3,15,22,4,1,25,26,18,13,10,30,2}, every extra x tick/.append style={yshift=-5mm, color = orange}, legend entries={only marks,{only marks, sharp plot}}]

as you can see in the picture, I have some xtra x tick labels in a different color than the oder x tick labels. In the x label I have a definition for the x tick labels and the extra x tick labels. To see which definition belongs the which x tick label, I would like to change the color of the second part of my x label "Name".

You can use \textcolor as in other situations where you want a colored word, i.e.

xlabel ={Anzahl \& \textcolor{orange}{Name}}

[Tex/LaTex] pgfplot: how to render 3dplot with colors black, white and gray

Simply add the option

colormap/blackwhite

to the axis.

colored gray, black to white

Alternatively, define your own colormap for different gray versions. For example, also as axis option:

colormap = {whiteblack}{color(0cm)  = (white);color(1cm) = (black)}

colored gray, white to black

You define a distance between some colors, tell colors (like with xcolor and pgf/TikZ syntax in general), the color space will be linear interpolated. You can read more details about color maps in the pgfplots manual in 4.7.6 Color Maps.

[Tex/LaTex] Graphing trigonometric functions, axes labeled with tick marks

You've asked quite a few questions! It's generally best to ask one, focused question on this site ;)

But, here's an attempt to get through your questions....

Labels, such as $y = \sin(x), would make the graphs more presentable. I guess directly under the y-axis.

You could use, for example,

\begin{axis}[
    Axis Style,
    xtick={
        -6.28318, -4.7123889, -3.14159, -1.5708,
        1.5708, 3.14159, 4.7123889, 6.28318
    },
    xticklabels={
        $-2\pi$, $-3\pi/2$, $-\pi$, $\pi/2$,
        $\pi/2$, $\pi$, $3\pi/2$, $2\pi$
    },
    ylabel={$y=\sin(x)$}, %<---- new bit
]

or else, for example,

...
\addplot [mark=none, ultra thick, blue] {sin(deg(x))};
\addlegendentry{$y=\sin(x)$} %<---- new bit
...

You might also want to adjust the legend position using legend pos=...

Arrowheads should be at both ends of the axes. They are currently at one end.

You can use,

\pgfkeys{/pgfplots/Axis Style/.style={
    width=.3\textwidth, %height=5cm,
    axis x line=center, 
    axis y line=middle, 
    samples=100,
    ymin=-1.5, ymax=1.5,
    xmin=-7.0, xmax=7.0,
    domain=-2*pi:2*pi,
    axis line style=<->,  %<----- new bit
}}

or otherwise use pgfplotsset (as demonstrated below).

The scale is suitable for the graphs of the sine and cosine functions but not for the tangent function. Maybe have the y-axis include -10 and 10.

Try using, for example,

\begin{axis}[
    Axis Style,
    xtick={-6.28318, -4.7123889, ..., 6.28318},
    scaled x ticks={real:3.1415},
    xtick scale label code/.code={},
    ymin=-10,ymax=10, %<---- new bit
]

Changing the scale for this graph may have the labels along the axes drawn over by the graph of the tangent function. Is there a code for putting labels (in nodes) over other features of a graph?

I believe you want the axis on top key for this.

Currently, the y-axes of the three graphs are aligned. How can I have the x-axes are aligned?

Remove the blank lines between your figures - note that you'll need to adjust the text width to get them to fit nicely - consider the geometry package for this.

What does mark=none instruct TikZ to do? What other options are there for mark?

mark=none means that you only get the curve, and not circles (or other marks) at the sample points along the way. There are a lot of other options - see Section 4.7 of the pgfplots for details.

Here's a complete bit of code to play with that implements the things I have mentioned.

% arara: pdflatex
% !arara: indent: {overwrite: yes}
\documentclass{article}
\usepackage{pgfplots}
\usepackage[margin=1cm]{geometry}
\pgfplotsset{Axis Style/.style={
    width=.3\textwidth, %height=5cm,
    axis x line=center,
    axis y line=middle,
    samples=100,
    ymin=-1.5, ymax=1.5,
    xmin=-7.0, xmax=7.0,
    domain=-2*pi:2*pi,
    axis line style=<->,
}}
