Tikz diagrams and node placements












3















I'm designing a diagram for a 1-D potential well. I'm struggling to correctly place my a label below the right hand line. I resorted to drawing an invisible line and positioning the node at the end. Further to this, how do I add grey shading to the area outside of the red lines?



Cheers



documentclass[tikz,border=3.14mm]{standalone} 
begin{document}
begin{tikzpicture}
draw[-stealth] (-0.5,0) -- (pi,0) node[right]{(x)};
draw[-stealth] (0,-0.5) -- (0,4) node[above]{(V(x))};
draw[thick, red, ->, >=stealth] (0,0) -- (0,3) node[left, blue]{()};
draw[thick, red,->, >=stealth] (2.5,0) -- (2.5,3);
% node[draw] at (2.5,-0.2) node[right, black]{(a)};
draw[line width=0pt] (0,0) -- (2.5,0) node[below, black]{(a)};
end{tikzpicture}
end{document}

          begin{tikzpicture}

          Note that if you want to draw an invisible line, you should not use line width=0pt, because it is still greater that zero. Use path instead (in fact draw and path[draw] are the same):



          path (0,0) -- (2.5,0) node[below, black]{(a)};
