Sets the linestyle of the LinePlot
Linestyles may be either a word in the Gnuplot style, or a symbol
shortcut in the Matlab style. Some of the options do not have a
Matlab equivalent but do have a Gnuplot equivalent, or vice versa.
What this method does, is take the linestyles possible as defined by
PyVisi, and then does some conversion as best it can to get the
relevant output from (in this case) gnuplot.
Possible linestyles are:
1. lines ('-')
2. points ('o')
3. linespoints ('-o')
4. dots ('.')
5. dotted (':')
6. dashes ('--')
7. dotdashes ('-.')
