Using gStyle in python


I am new in using ROOT called by python and when building a plot,
I am currently trying to increase the space of the left margin using
the next lines, as the annotations on the y axis interfer with the y axis title :

    [i]      ....
           from ROOT import  gStyle
           class RootPlot():
             def __init__(...):
                 self.canvas = TCanvas(...)

This is accepted when the python program is launched but the plot
remains the same. I guess this is not written correclty : I do not know
how to link gStyle entity and the created canvas.

Can you tell me how to call correctly the gStyle entity ?

Thanks for your help,

You should manipulate the style before creating the canvases and drawing the histogram.
