silx.gui.plot.PlotWidget: Added yaxis arcsinh support with matplotlib backend #4306

Nice. This could also be a good opportunity to rework the backend API with normalization. Because actually, to set linear, we have to set |

I think I'll leave the opengl for somebody else :) |

Could you convert the text to a path so the icon does not rely on system fonts?
If you don't know how to do it, i can show you.

Would be best to change the backend to have a single place where to set scale for yaxis.
I would replace setYAxisLogarithmic and setYAxisArcsinh by a setScale.
The backend are not marked as private with an _ but they should have and we don't keep the compatibility.

Same as above, _internalSetLogarithmic and _internalSetArcsinh could be replaced by a _internalSetScale

Adding a new axis scaling changes its control from a boolean to an enum (it should have been so since the beginning).
It would make sense to me to replace yAxisLogarithmicAction with a toolbutton with a drop-down.
