PlotItem --+ | Func
Represents a mathematical expression to plot.
Func represents a mathematical expression that is to be computed by gnuplot itself, as if you would type for example:gnuplot> plot sin(x)into gnuplot itself. The argument to the contructor is a string that should be a mathematical expression. Example:
g.plot(Func('sin(x)', with='line 3'))As shorthand, a string passed to the plot method of a Gnuplot object is also treated as a Func:
g.plot('sin(x)')

Construct a 'PlotItem'. Keyword options: 'with=<string>' -- choose how item will be plotted, e.g., with='points 3 3'. 'title=<string>' -- set the title to be associated with the item in the plot legend. 'title=None' -- choose 'notitle' option (omit item from legend). Note that omitting the title option is different than setting 'title=None'; the former chooses gnuplot's default whereas the latter chooses 'notitle'.
