Graphics, Figures & Tables ⇒ Tikz multi line text nodes

[ahmed]

hello everybody
i wanna to put the equation in the ellipse in a new line and the symbol "\\" doesn't work inside the text braces.
i wanna any methode to put the equations in new line
as it is not like good to put it in the same line with the text.
also another problem , the figure is shifted to the right
any solution
here is the code

Code: Select all

thanks in advance

Hi,

for the first problem, you can use \parbox commands; i.e., instead of

Code: Select all

\node [cloud, below of=location,node distance=2cm] (median)               
  {Median \\$q_{0.5}$ };

you can use something like this:

Code: Select all

\node [cloud, below of=location,node distance=2cm] (median) 
  {\parbox{1.5cm}{\centering Median \\$q_{0.5}$} };

Regarding the other issue, perhaps you should consider scaling the whole object.

thanks
it works well , i also found another method whic it to
put the text width in the style this makes the pgf fell the existence of the \\ , i don't know why

Code: Select all

\tikzstyle{cloud} = [draw, ellipse,fill=red!20, node distance=3cm,text width=3cm,text centered, minimum height=2em]

but for the second problem, i donot know how to make the resizing you said without affecting the size of picture.

If you want to maintain the actual size of the diagram, it will exceed the right margin; you could use a \makebox command to center it:
