Method toPainter

! Renders the plot using the passed \a painter. The plot is sized to \a width and \a height in pixels. If the \a painter's scale is not 1.0, the resulting plot will appear scaled accordingly. \note If you are restricted to using a QPainter (instead of QCPPainter), create a temporary QPicture and open a QCPPainter on it. Then call \ref toPainter with this QCPPainter. After ending th

  \see toPixmap
