Add a 1D curve given by x an y to the graph.

Curves are uniquely identified by their legend. To add multiple curves, call addCurve() multiple times with different legend argument. To replace an existing curve, call addCurve() with the existing curve legend. If you want to display the curve values as an histogram see the histogram parameter or addHistogram().

When curve parameters are not provided, if a curve with the same legend is displayed in the plot, its parameters are used.

Parameters:

x (numpy.ndarray) – The data corresponding to the x coordinates. If you attempt to plot an histogram you can set edges values in x. In this case len(x) = len(y) + 1. If x contains datetime objects the XAxis tickMode is set to TickMode.TIME_SERIES.
y (numpy.ndarray) – The data corresponding to the y coordinates
