By default, Pyxplot generates its own entry in the legend of a plot for each dataset plotted. This default behaviour can be overridden using the title modifier. The following example labels a dataset as ‘Dataset 1’:
plot sin(x) title 'Dataset 1'
If a blank string, i.e. "", is supplied, then no entry is made in the plot’s legend for that dataset. The same effect can be achieved using the notitle modifier.
