Not sure where else to add a comment:

I would like to add another interesting Python-based reference tool to the mix:

guiqwt: [GitHub - PlotPyStack/guiqwt: Efficient 2D plotting Python library based on PythonQwt](https://github.com/PierreRaybaut/guiqwt)

It appears to include facilities enabling people to easily add fancy interactivity to their plots.

You can install `guiqwt` on an ubuntu system:

```julia
sudo apt-get install python-guiqwt

```

You can then try out sample tests by running `guiqwt-tests`.

For example:

- **cross\_section.py** : Provides x & y cross-section markers that, when dragged over a MRI/CT-scan image, displays the 1D signal of that cross-section.
- **computations.py** : Provides a means to select a region (displayed as a transparent red section) that tabulates various signal statistics.
- **fit.py** : Uses the bounds “tool” to select the region over which to fit noisy data with an ideal signal model.
- **plot.py** : Provides a widget that allows you to select curves more easily (maybe the legend itself could be implemented as a widget).
- …See other examples for more…

A few visual examples…

I would also like to see user-draggable “delta markers” being used in future visualization tools as well. Maybe something similar to what is implemented in the master branch of InspectDR.jl:
