Support for more than one axis on each side

[nicoddemus]

Hi,

Currently PythonQwt supports one axis on each side (one axis on the left, right, top, and bottom).

At ESSS we need more axes than that, so we implemented such a support in Qwt directly a few years ago, in an internal fork.

This patch implements a total of 4 axes on each side, so there is yLeft, yLeft1, yLeft2, etc.

Given Qwt is no longer maintained, we are now porting our code base to PythonQwt, however we really need support for more axes than the default ones provided.

We at ESSS will need to implement this, the options as we see it are either as patch to PythonQwt(1), or on top of it in our internal codebase (2).

My question is if this is something that is interesting to have in PythonQwt itself? If so, we would be happy to implement it as a patch and contribute it to the project. If not however (and we understand this might be the case), we will try to go with (2) as this is easier for us to maintain going forward than a fork.

Cheers!

Let me think about it.

By the way, our main concern right now regarding the future of PythonQwt is this issue: a performance issue which is actually related to PythonQwt itself. Currently, I have no clue how to fix it in PythonQwt. I even thought of a complete rewrite of the library: creating a new plotting library (still pure Python based on QtPy) providing only the plotting primitives required by PlotPy (that is canvas, axes and curves).

OK thanks @PierreRaybaut for the response. Please let me know once you have a decision (or even a general feeling would be OK).
