__init__() takes exactly 5 arguments (4 given) error in contour plot
I am trying to make a contour plot of a complex valued function. Let say it is g(z).
I have imported the complex root and ContourPlot command by doing following:
from sage.rings.polynomial.complex_roots import complex_roots
from sage.plot.contour_plot import ContourPlot
I have even successfully plot the 3d-Plot, but I encountered an error stating:
__init__() takes exactly 5 arguments (4 given)
My command is:
C=ContourPlot(lambda x,y:float(green(x+y*I)),(-5,5),(-5,5))
It seems that I did not miss the fifth argument, I tried to add in some commands, such as plot_points, but then Sage said it did not expect these commands..
What did I miss? Thank you!!
Please declare explicitly a function that should be passed to the one or the other contour-plot-function. (I do not have the
greenfunction.) Note that in the description of the method (for instance usingsage: sage.plot.contour_plot.ContourPlot??in the sage interpreter, or finding the source on the hard disk) we need arguments like here:C = ContourPlot([[1,3],[2,4]], (1,2), (2,3), options={}). The version may also help potential answerers.
