\brief Insert a legend
If the position legend is \c QwtPlot::LeftLegend or \c QwtPlot::RightLegend
the legend will be organized in one column from top to down.
Otherwise the legend items will be placed in a table
with a best fit number of columns from left to right.
insertLegend() will set the plot widget as parent for the legend.
The legend will be deleted in the destructor of the plot or when
another legend is inserted.
Legends, that are not inserted into the layout of the plot widget
need to connect to the legendDataChanged() signal. Calling updateLegend()
initiates this signal for an initial update. When the application code
wants to implement its own layout this also needs to be done for
rendering plots to a document ( see QwtPlotRenderer ).
\param legend Legend
\param pos The legend's position. For top/left position the number
of columns will be limited to 1, otherwise it will be set to
unlimited.
\param ratio Ratio between legend and the bounding rectangle
of title, canvas and axes. The legend will be shrunk
if it would need more space than the given ratio.
The ratio is limited to ]0.0 .. 1.0]. In case of <= 0.0
it will be reset to the default ratio.
The default vertical/horizontal ratio is 0.33/0.5.
