It is uneasy to configure the bounds of a Graph

[mbaudin47]

In the following message:

https://stackoverflow.com/questions/63309636/how-to-set-axes-limits-on-openturns-viewer

the answers reveal that configuring the bounds of a graph is not easy. The set/getBoundingBox is not straightforward to use, because we must create an Interval first.

A more simple API would be based on setXMin, setXMax, setYmin, setYmax:

import openturns as ot
import openturns.viewer as otv
n = ot.Normal()
graph = n.drawPDF()
graph.setXMin(-1.0)
graph.setXMax(2.0)
graph.setYMin(-3.0)
graph.setYMax(1.0)

This API does not prevent from retaining the current boundingBox.

Another way to improve the situation would be to add this example to the following help page:
