Hello. One method could be the following one where *L* is a list of points. We note *xMin* and *xMax* the smallest and biggest abscissa respectively.
1. Add two extra points *(xMin , -inf)* and *(xMax , -inf)* to the list * L*. We obtain the list *L**L*. 2. Compute the convex hull of the list of points *L**L*. 3. Remove the three lines with vertex *(xMin , -inf)*or *(xMax , -inf)*. 4. Draw only the remaining lines. A good candidiate for *(-inf)* could simply be *(yMin - 10)* for example where *yMin* is the smallest y-coordinate.
