I want to draw following line, its tip at right), as follows:

image 1 image 2

tex file:

\documentclass[10pt,journal,compsoc]{IEEEtran}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
    \draw (0,0) grid (1,-1);
    \draw [semithick](0.8,-0.1)--+(-0.6,-0.7);
\end{tikzpicture}
\end{document}

enter image description here

Here I was not able to draw perfectly symmetric line inside the box and couldn't draw the tip of the line as shown above.

Use the arrows.meta library with Triangle Cap to get those line tips.

I changed your grid to rectangle to get nicer corners. To place the line along the diagonal, you can draw from corner to corner and use shorten as in the code below:

\documentclass[10pt,journal,compsoc]{IEEEtran}
\usepackage{tikz}
\usetikzlibrary{arrows.meta}
\begin{document}
\begin{tikzpicture}
    \draw (0,0) rectangle (1,-1);
    \draw[Triangle Cap-Triangle Cap, shorten <=2mm, shorten >=2mm] [semithick](0,-1)--++(1,1);
\end{tikzpicture}
\end{document}

  • Is it also possible to center the line in the box?

    Given the grid coordinates, you could use (.2,-.8)--++(.6,.6), or use (0,-1)--++(1,1) and add shorten <=2mm, shorten >=2mm.

  • Should I write shorten <=2mm, shorten >=2mminside the draw[]?
