How to modify a Contour once it has been put into a Graph?

[regislebrun]

What happened?

If I want to modify the colorbar location of a Contour once it has been put into a Graph, I don't have access to the Contour interface but only the interface of Drawable:

import openturns as ot

g = ot.Normal(2).drawPDF()
contour = g.getDrawable(0)
# Impossible to change the colorbar location
contour.setColorBarPosition("") # fails

How to reproduce the issue?

Use the given script

You can do it this way;

import openturns as ot

g = ot.Normal(2).drawPDF()
contour = g.getDrawable(0).getImplementation()
contour.setColorBarPosition("")

@regislebrun : I suggest to update the title to "How to remove the colorbar of a contour plot?". I also suggest to close this issue, since the answer was given by @josephmure

@mbaudin47: The problem is not bound to the colorbar location but for all the methods of Contour not accessible from the Drawable interface. BTW many of these methods are poorly documented, such as isVminUsed()/isVmaxUsed(). It is stated that they are accessors to the related flag, but one has no clue on why it is usefull to get this information, in particular we don't know for what this value is used.

Vmin and vmax are documented in https://matplotlib.org/stable/api/_as_gen/matplotlib.pyplot.contour.html so I guess the answer is to link to this page.
