# How can i change the label of y-axis in my graph

Here in my MWE, you will find a histogram. In which i would like to change labeling of y-axis. I want {10, 20, 30, .....100} in place of {1 , 2 , ..10} Please make correction in same as well as provide any other alternate for changing and making axis label in smooth way.

\usepackage{pgfplots}
\pgfplotsset{compat=1.7}

\begin{document}
\begin{tikzpicture}
\draw[<->] (-1cm,0cm) -- (15cm,0cm) node [right] {\large$x$};  %Abzisse

\draw[<->] (0cm,-1cm) -- (0cm,15cm) node [left] {\large$y$};  %Ordinate

\foreach \x in {1,...,14}
\draw[gray!50, text=black] (0 cm,\x cm) -- (14 cm,\x cm)
node at (-0.5 cm,\x cm) {\x};

\draw (1cm,0cm) rectangle (2cm,3cm) node at (1.5cm,3.4cm) {14};

\definecolor{myblue}{HTML}{92dcec}

\draw[fill=myblue] (1cm,0cm) rectangle (2cm,3cm)

• Just FYI, you don't need to add \definecolor{myblue}{HTML}{92dcec} every time; you just need to use it once, at the beginning, and then it will be defined throughout your document. – Arun Debray Dec 16 '15 at 5:16

Maybe this can help you. You can avoid writing the same stuff several times.

I use \the\numexpr\x*10 for calculating the labels and then each bar according with your design.

\documentclass[border=5mm]{standalone}

\usepackage{pgfplots}
\pgfplotsset{compat=1.7}

\begin{document}
\begin{tikzpicture}
\draw[<->] (-1cm,0cm) -- (15cm,0cm) node [right] {\large $x$};  %Abzisse

\draw[<->] (0cm,-1cm) -- (0cm,15cm) node [left] {\large $y$};  %Ordinate

\foreach \x in {1,...,14}
\draw[gray!50, text=black] (0 cm,\x cm) -- (14 cm,\x cm) node at (-0.5 cm,\x cm)
{\the\numexpr\x*10};

\definecolor{myblue}{HTML}{92dcec}

\foreach \y [count=\x from 1] in {14, 56, 60, 36, 74, 62, 48}
{\draw[fill=myblue] (\x,0) rectangle (\x + 1, \y / 10);
\node at (\x+.5,\y / 10 + .4) {\y};};

\end{tikzpicture}


\end{document}

This is the output:

• A big big thanks to you.......i find something new hints from this . – snehal Dec 16 '15 at 6:15

Another solution :

 \foreach \x / \y in {
1/10,
2/20,
3/30,
4/40,
5/50,
6/60,
7/70,
8/80,
9/90,
10/100,
11/110,
12/120,
13/130,
14/140
}
\draw[gray!50, text=black] (0 cm,\x cm) -- (14 cm,\x cm)
node at (-0.5 cm,\x cm) {\y};


This solution allows you to put whatever you want in this y-axis label.

You can just add a 0 to the text at each node on your y-axis:

\foreach \x in {1,...,14}
\draw[gray!50, text=black] (0 cm,\x cm) -- (14 cm,\x cm)
node at (-0.5 cm,\x cm) {\x 0}; % <-- here


You can also replace the {\x 0} with a calculation {\the\numexpr\x * 10}, as in this answer, i.e.

\foreach \x in {1,...,14}
\draw[gray!50, text=black] (0 cm,\x cm) -- (14 cm,\x cm)
node at (-0.5 cm,\x cm) {\the\numexpr\x*10};


This has the advantage that you can replace 10 with any other number and get them numbered by twos or fives or whatever you want.

Either way, here's what the output looks like.

• I wanna ask one more question related to previous one. – snehal Dec 16 '15 at 8:07
• How can i keep a blank of 1cm between each bar in the above MWE. – snehal Dec 16 '15 at 8:11
