Detailed Description

Data structure containing info about properties of a family of curves and the curve list.

A curve family is a list of curves sharing the same properties. The Y data for a curve family is defined in the columns of a 2-D numpy array.

The class attributes and methods will not be documented, because the names are self-explanatory and the code is trivial.

def dbplot.CurveFamily.setLegendItems	(	self,
		legend = `None`,
		updateLegend = `False`
	)

After creating a legend for the QWtPlot, this method will assign the QwtLegendItem of the first curve to self.legendItem, and remove the other QwtLegendItem's from the QwtLegend layout.

Parameters

legend	= QwtLegend in QWtPlot. If equal to None, the curves are being updated and the QwtLegend handle is already stored in self.legend . Default None.
updateLegend	= Call curve.updateLegend() for the 1st curve. Default False.
