Graphics, Figures & Tables ⇒ Connecting Line between Points not straight

[mayankmi]

Hey. I used this code, but the line joining two points (0.5,0.7) to (1,0.7) is not exactly straight. It is a bit curved. I want to make this line straight.

Code: Select all

\documentclass[11pt]{article}
\usepackage[T1]{fontenc}
\usepackage{pgfplots}

\pgfplotsset{compat=newest}

\begin{document}
  \begin{figure}[!htb]
    \centering
    \begin{tikzpicture}
      \begin{axis}[
        width=12cm,
        height=8cm,  
        grid=both,
        xmin=0,
        xmax=1,
        ymin=0,
        ymax=1.5,
        xlabel={Weighing factor for NDT test (w)},
        ylabel={Trust factor (T)}
      ]
        \addplot[smooth,mark=*,black] plot coordinates {
          (0,1.3)
          (0.5,0.7)
          (1,0.7)
        };
        \addlegendentry{Trust factor  T = 1.3 - 0.5 w};
      \end{axis}
    \end{tikzpicture}
    \caption{Proposed trust factor for NDT tests}
    \label{Proposed trust factor for NDT tests}
  \end{figure}
\end{document}

The first part isn't straight either. Just remove the smooth option from your \addplot command.

Code: Select all

\documentclass[11pt]{article}
\usepackage[T1]{fontenc}
\usepackage{pgfplots}

\begin{document}
  \begin{tikzpicture}
    \begin{axis} 
      \addplot[
%        smooth,
        mark=*,
        black
      ] plot coordinates {
        (0,1.3)
        (0.5,0.7)
        (1,0.7)
      };
    \end{axis}
  \end{tikzpicture}
\end{document}
