# Plot using Hobby

Help me to plot the following plot using Hobby.

I have tried to plot it. My code is

\begin{tikzpicture}[use Hobby shortcut]
\draw (-.3 ,1).. (0, 0) .. ( 1.2 , 0 ) .. ( 0 , 0 ) .. (-.3 ,-1);
\draw (.45, 0) .. ( .9 , 0 ) .. ( .6 , 0 ) .. ( .7 , -0.01);
\draw  (-.15, 1.2).. (-.01, .2) ..(.01, .22).. (.6, .1) .. ( 1.3 , 0 ) .. ( 0 , -.1 ) .. (-.3 ,-1.2);
\node[inner sep=1pt,circle,fill=black] at  ( .7 , -0.01) {};
\end{tikzpicture}


Please correct my code to get the desired fig. Also I want to write HL adjacent to the Fig.

The figure can be written as in the following example.

• The arrow tips are placed as decoration markings. See the answer of Alain Matthes and section 30.5.1 Arrow Tip Markings of the TikZ & PGF manual.

• Styles are defined to make the \draw commands more compact:

• Style /my marks collect the arrow mark settings via option mark.
• arrow mark and reversed arrow mark sets an arrow tip or an arrow tip in reversed direction. The mark option setting is stored in /my marks.
• Style do marks installs the decoration with the arrow tip markings on the path. It used /my marks,therefore it must be specified after (reversed) arrow mark.
• The label "HL" is put right below the drawing, flushed to the right.

• BTW, the vertical coordinate values are flipped, therefore the y unit is set to a negative value (y=-1bp).

(I had taken the coordinates from the image positions in gimp, where the vertical positions go from the top to the bottom.)
